When we think of Hollywood fitness icons, Lucy Hale often tops the list. The former Pretty Little Liars star has transitioned from a teen idol to a fitness powerhouse, frequently sharing glimpses of her grueling workouts on social media. While her routine is diverse, incorporating everything from distance running to heavy lifting, there is one piece of equipment that consistently stands out in her arsenal: the fitness sled. Often referred to as a Prowler or a dragging sled, this tool is the secret behind her incredibly sculpted arms and defined back. Sled training is unique because it offers a blend of cardiovascular conditioning and functional strength that is difficult to replicate with traditional dumbbells or machines. In this comprehensive guide, we will dive deep into the mechanics of sled training, why it is so effective for upper body aesthetics, and how you can implement Lucy Hale’s favorite moves into your own routine to achieve a red-carpet-ready physique.
The Science of Sled Training for Upper Body Definition
To understand why sled training works so well for sculpting the arms and back, we have to look at the biomechanics of resistance. Most traditional weightlifting involves both a concentric phase (shortening the muscle, like lifting a weight) and an eccentric phase (lengthening the muscle, like lowering the weight). While eccentric loading is great for muscle growth, it is also the primary cause of delayed onset muscle soreness (DOMS). Sled training, conversely, is almost entirely concentric. When you pull or push a sled, there is no “negative” or lowering phase. This allows you to train with high intensity and high frequency without the debilitating soreness that often follows a heavy gym session.
For the upper body, the sled provides constant tension. Unlike a cable machine where the weight might momentum-swing, a sled requires a continuous application of force. If you stop pulling, the sled stops moving. This constant tension is a primary driver of sarcoplasmic hypertrophy, which leads to that “filled out” and toned look in the shoulders, biceps, and lats. Furthermore, because sled work is often performed in a metabolic conditioning format, it helps strip away body fat, revealing the hard-earned muscle underneath. Lucy Hale’s physique is a testament to this combination: lean, functional, and powerful.
Why Lucy Hale Swears by the Sled
Lucy Hale has often credited her trainer, Kira Stokes, with introducing her to the world of functional “stoked” movements. The sled fits perfectly into this philosophy because it is a full-body integrator. While we are focusing on the arms and back, it is impossible to move a heavy sled without engaging the core, glutes, and legs. This high caloric burn is one reason why Hale can maintain her lean frame while building significant strength.
Another reason for the sled’s popularity in celebrity circles is its efficiency. In a 20-minute sled session, you can accomplish what might take an hour using separate cardio and strength machines. For a busy actress, time is the most valuable commodity. The sled allows her to build “pull” strength—essential for a defined back—while simultaneously pushing her heart rate into the fat-burning zone. It is also an adaptable tool; whether she is training for a specific role or just staying in shape for her personal well-being, the sled can be loaded light for speed or heavy for raw power.
Essential Sled Exercises for Sculpted Arms
If you want arms like Lucy Hale, you need to move beyond the standard bicep curl. The sled offers unique angles of resistance that target the arms from all directions. Here are the cornerstone exercises for arm definition:
- Sled Bicep Curls: Attach a long strap or rope to the sled. Facing the sled, walk backward until the straps are taut. Perform a curl by pulling the handles toward your shoulders, then take a few steps back to reset the tension and repeat. This move keeps the biceps under tension for much longer than a standard dumbbell curl.
- Sled Tricep Extensions: Turn away from the sled, holding the straps over your shoulders. Lean forward slightly and extend your arms forward, mimicking a cable overhead extension. As you move forward, the sled provides a steady resistance that fries the long head of the triceps, which is responsible for the “horseshoe” shape on the back of the arm.
- The Hand-Over-Hand Rope Pull: This is perhaps the most effective move for forearm and bicep thickness. Sit or stand at one end of a long rope attached to the sled. Pull the sled toward you using only your arms, hand over hand. This requires incredible grip strength and creates a massive pump in the forearms and biceps.
When performing these, focus on the mind-muscle connection. Don’t just jerk the sled; feel the muscles in your arms contracting to overcome the friction of the sled against the floor.
Building a Strong, Tapered Back with Pulling Variations
A defined back is the hallmark of a fit physique, creating the illusion of a smaller waist. Lucy Hale’s workouts often emphasize the “v-taper” through various pulling motions. The sled is an elite tool for this because it allows for heavy loading with minimal risk of lower back injury compared to traditional bent-over rows.
Seated Sled Rows: Sit on the floor or a low bench facing the sled with your feet braced. Using a handle attachment, pull the sled toward your chest, focusing on squeezing your shoulder blades together. Because you are seated, you eliminate the ability to use leg momentum, forcing the lats and rhomboids to do all the work. This is excellent for building back thickness.
Standing Face Pulls with the Sled: Attach straps and hold them at eye level. As you walk backward, pull the handles toward your forehead, flaring your elbows out. This targets the posterior deltoids and the traps, which are crucial for posture and that “lifted” look in the upper back. Poor posture can make even the most fit person look less toned; face pulls are the antidote.
Low-to-High Sled Pulls: By starting with your hands low and pulling the sled up toward your hips as you move, you engage the lower lats. This helps create that sleek, sculpted line from the armpit down to the waist.
The Role of Core Stability in Sled Work
You cannot have a strong back and arms without a stable base. Every time Lucy Hale pulls or pushes a sled, her core is working overtime to stabilize her spine. This is known as anti-rotation and anti-extension training. When you pull a heavy sled, the weight wants to pull you out of alignment. Your obliques, transverse abdominis, and rectus abdominis must fire to keep you upright.
To maximize core engagement during your sled workout, focus on “bracing.” Imagine someone is about to punch you in the stomach; that tightness you feel is the bracing you should maintain throughout the movement. This not only protects your spine but also ensures that the force you generate with your arms is efficiently transferred to the sled. This “hidden” ab workout is why sled enthusiasts often have very tight, defined midsections without ever doing a single crunch.
Designing Your Lucy Hale-Inspired Sled Workout
Ready to hit the turf? To train like Lucy, you need a balance of strength and cardiovascular endurance. Here is a sample “Sculpt and Shred” sled routine you can do twice a week:
- Warm-up: 5 minutes of light sled pushing (empty sled) to get the blood flowing to the joints.
- The Heavy Pull: Hand-over-hand rope pulls (4 sets of 15 yards). Focus on heavy weight and slow, controlled movements. Rest 90 seconds between sets.
- The Sculptor: Sled Bicep Curls into Tricep Extensions (Superset). Do 10 curls, immediately followed by 10 extensions. Repeat for 3 rounds.
- The Posture Builder: Seated Sled Rows (3 sets of 20 yards). Use a weight that allows you to maintain a flat back and proud chest.
- The Finisher: Sled Sprints (Pushing). 5 rounds of 20-yard sprints with 30 seconds of rest. This will spike your heart rate and maximize fat oxidation.
As you get stronger, don’t just add more weight. You can increase the intensity by decreasing rest periods, increasing the distance, or increasing the speed of the movements. This is the principle of progressive overload, which is essential for seeing continuous changes in your body.
Common Mistakes to Avoid for Safety and Results
While sled training is generally safer than barbell training, form still matters. The most common mistake is “rounding the back” during pulls. This puts unnecessary stress on the lumbar spine. Always keep your chest up and your shoulders packed down and back. If you find your back rounding, the weight is likely too heavy.
Another mistake is using too much momentum. In the bicep curl or row variations, it is easy to use a “rocking” motion with your whole body to get the sled moving. This takes the tension off the target muscles. If the goal is sculpted arms, you want the arms to do the work. Keep your torso as still as possible.
Lastly, don’t neglect your footwear. Sled training requires significant traction. Wearing thin-soled lifestyle sneakers can lead to slipping, which reduces the amount of force you can apply and increases the risk of a calf strain. Opt for cross-trainers or shoes with a grippy rubber sole designed for turf work.
Nutrition and Recovery for Muscle Definition
Lucy Hale often speaks about the importance of fueling her body. You cannot sculpt muscle if you aren’t eating enough protein. Protein provides the amino acids necessary to repair the micro-tears created during your sled session. Aim for 0.8 to 1 gram of protein per pound of body weight to support muscle growth and recovery.
Hydration is also key, especially with sled work, which tends to be very sweaty. Electrolytes (sodium, potassium, magnesium) are essential for muscle contractions. If you find yourself cramping during a sled pull, it’s a sign your mineral balance is off. Furthermore, because sled training is concentric-focused, you can recover faster, but you still need quality sleep. Aim for 7-9 hours of sleep to allow your endocrine system to release growth hormone, which facilitates the “sculpting” process.
Conclusion
Sled training is the “hidden gem” of the fitness world, and Lucy Hale’s impressive physique is the perfect advertisement for its benefits. By incorporating sled pulls, rows, and curls into your routine, you can build a back that is both strong and elegant, and arms that are defined without looking bulky. The beauty of the sled lies in its versatility; it is a tool for the beginner and the elite athlete alike. Whether you are looking to improve your functional strength, lose weight, or simply look better in a sleeveless dress, the sled is your ticket to success. Start slow, focus on your form, and soon you’ll be reaping the rewards of this Hollywood-approved workout secret.
Mastering Surface Friction: How Ground Texture Alters Upper Body Engagement
While the weight loaded onto the sled is the most obvious variable, the surface you are training on—the coefficient of friction—dictates the specific stimulus your arms and back receive. In a high-end facility like those Lucy Hale frequents, you will likely find high-density polyethylene (HDPE) turf. This surface is designed for a smooth, consistent glide. On turf, the resistance is predictable, which allows for high-velocity movements. This is ideal for “power pulling,” where the goal is to move the sled as fast as possible to recruit Type II fast-twitch muscle fibers in the lats and deltoids. If you are training on turf, focus on explosive, snappy repetitions to build that athletic, “popping” muscle definition.
Conversely, if you take your sled workout to a rubberized weight room floor or a textured outdoor concrete path, the friction increases exponentially. On these “sticky” surfaces, the sled requires a massive amount of initial force just to break the static friction. This translates to a high-intensity isometric load on the biceps and forearms the moment you begin the pull. For those looking to build significant forearm thickness and grip strength—essential for that “strong-not-just-toned” look—training on high-friction surfaces is a secret weapon. It forces the muscles of the back to stay in a state of near-maximal contraction just to keep the sled from stopping. When training on high-friction surfaces, reduce the plate weight by 30-40% compared to what you would use on turf, and focus on a slow, grinding “time under tension” approach.
An often-overlooked edge case is training on natural grass. Grass provides inconsistent resistance; a patch of damp soil or a thick tuft of weeds can suddenly increase the drag. This unpredictability is actually a phenomenal tool for core and back stabilization. As the resistance fluctuates, your internal obliques and the deep stabilizers of the scapula must micro-adjust constantly. This “reactive” strength training is what gives celebrities like Hale that effortless, functional posture. If you’re training outdoors, embrace the unevenness—it’s turning a standard row into a multi-planar stability challenge.
Grip Mechanics and Hand Positioning: The Subtle Art of Targeted Sculpting
To truly replicate the “Stoked” method and achieve precision sculpting, you must look at how your hands interface with the sled straps or handles. Most gym-goers default to a standard overhand grip, but varying your hand position can shift the workload between the different heads of the biceps and the various sections of the back. For instance, using a supinated (palms-up) grip during a sled pull significantly increases the activation of the biceps brachii. This is the key to creating that “peak” on the arm. When performing a bicep-focused sled pull, ensure your elbows are pinned to your ribcage to prevent the lats from taking over the movement.
For back width, a wide, pronated (palms-down) grip on a horizontal bar attachment is superior. This positioning flares the elbows out, putting the focus on the latissimus dorsi and the teres major. If your goal is back thickness—the “3D” look when viewed from the side—switch to a neutral grip (palms facing each other) using a V-bar or parallel handles. This allows for a deeper retraction of the shoulder blades, pulling the sled toward your lower ribcage and engaging the rhomboids and middle traps. Lucy Hale’s workouts often incorporate these subtle shifts to ensure no muscle fiber is left unstimulated.
Advanced trainees should also experiment with the “hook grip” or “fat grips.” Attaching thick rubber sleeves to your sled handles increases the diameter, making it significantly harder to close your hand. This doesn’t just build a crushing grip; it creates a phenomenon called “irradiation.” When you squeeze a handle harder, the neural drive to the surrounding muscles (the forearms, biceps, and even the shoulders) increases. By simply using a thicker grip during your sled rows, you can actually recruit more muscle fibers in your upper back than you would with a standard handle. It’s a high-level hack for maximizing the efficiency of every yard pulled.
Incorporating Isometrics and Tempo into Sled Drills
One of the reasons sled training is so effective for aesthetics is the ability to manipulate tempo without the safety risks associated with free weights. In a traditional barbell row, holding a “dead stop” at the top of the movement can be taxing on the lower back. With a sled, you can incorporate “Isometric Hold Pulls” to build incredible muscle density. To do this, pull the sled toward you until your elbows are past your torso, then hold that maximum contraction for 3 to 5 seconds while resisting the sled’s desire to stay still. This creates a massive amount of metabolic stress, which is a primary trigger for muscle hypertrophy.
Tempo training can also be applied to the “return” phase of a move, even though the sled lacks a traditional eccentric. For example, during a sled bicep curl, instead of simply stepping back to reset the tension, try a “walking curl.” As you walk backward, maintain a partial curl (about 90 degrees) the entire time. This constant, static-dynamic tension is grueling but highly effective for “hardening” the muscle. It eliminates any “rest” periods within the set, forcing the arms to adapt to a continuous oxygen debt.
For those looking to improve explosive power—perhaps for sports or high-intensity athletic roles—try “Overspeed Pulls.” This involves using a lighter weight but moving your hands or feet as fast as humanly possible. The goal is to minimize the “ground contact time” of the sled. This type of training sharpens the nervous system and helps in developing a lean, wiry physique. By alternating between “Grind Sets” (heavy and slow) and “Speed Sets” (light and fast), you provide the body with a dual stimulus that prevents plateaus and keeps the metabolism elevated for hours after the workout.
Advanced Sled Attachments: Leveling Up Your Pulling Game
While the standard strap and handle setup is effective, adding specialized attachments can transform the sled into a total-body sculpting machine. One of the most effective tools to pair with a sled is a suspension trainer, like a TRX. By clipping the TRX handles to the sled, you introduce an element of instability. As you perform a sled row with suspension straps, the handles can move independently, forcing your rotator cuff and rear deltoids to work overtime to keep the movement path straight. This is an elite-level move for shoulder health and defining the small, intricate muscles of the upper back that are often missed by fixed machines.
Another “pro” attachment is the heavy battle rope. Instead of the usual hand-over-hand pull where the rope is already attached, try a “Dynamic Wave Pull.” This involves performing battle rope waves (up and down) while simultaneously walking backward and pulling the sled. This is an incredible cardiovascular challenge that also fries the shoulders and forearms. It requires a high level of coordination and “core-to-extremity” power transfer, making it a favorite for athletes who need to maintain upper body strength under extreme fatigue.
For those focusing on the “V-taper,” consider using a waist harness in conjunction with hand pulls. By attaching the sled to your waist and also holding handles in your hands, you can perform “Dual-Tension Rows.” As you walk backward, the harness pulls on your hips, engaging the lower body and core, while your arms perform rows against the same resistance. This creates a “total posterior chain” engagement that is impossible to replicate. It forces the lats to work in sync with the glutes and hamstrings, which is the foundation of functional, athletic movement and a balanced, aesthetic physique.
Scapular Health and the Prehab Benefits of Sled Work
Beyond the aesthetic benefits, sled training is a powerful tool for “prehab”—preventative rehabilitation. Many people suffer from “rounded shoulders” or “text neck” due to prolonged sitting. This posture is caused by weak rhomboids and overactive, tight chest muscles. The sled is the ultimate antidote because almost every upper body sled exercise is a “pulling” motion that emphasizes scapular retraction (squeezing the shoulder blades together). Unlike a seated cable row, which can sometimes allow you to “cheat” by leaning back, a sled row requires you to maintain a stable, upright torso against a moving resistance.
Specifically, the “Sled Face Pull” is a foundational movement for shoulder longevity. By pulling the handles toward your forehead and focusing on external rotation of the shoulders, you strengthen the infraspinatus and teres minor—two of the four rotator cuff muscles. Strong rotator cuffs are the “insurance policy” for your shoulders, allowing you to perform heavy presses and overhead movements without pain. Because the sled provides constant tension, it also activates the serratus anterior—the “boxer’s muscle” that sits on the ribs. A well-developed serratus not only looks impressive but also ensures that your shoulder blade moves smoothly along your ribcage.
For those with history of wrist or elbow issues, the sled offers a “joint-friendly” way to train heavy. Since there is no “dropping” of the weight and no jarring impact, the stress on the joints is remarkably low. The resistance is purely frictional and horizontal, which removes the compressive force on the spine that you get with a barbell. This makes it an ideal choice for older athletes or anyone recovering from an injury who still wants to maintain their “killer” upper body routine without the risk of a flare-up.
Metabolic Finishes and “The Burn”: Upper Body Sled Complexes
To maximize the “shred” factor of Lucy Hale’s workout, you can utilize sled complexes—performing multiple exercises back-to-back without letting go of the handles. A “complex” keeps the heart rate in the anaerobic zone, turning a strength session into a potent fat-burning event. A classic example is the “Pull-Push-Row” complex. Start by pulling the sled backward for 20 yards using a bicep-dominant pull, immediately turn around and push the sled back to the start using the high handles (targeting the chest and triceps), and finally, perform 15 seated rows. This 90-second burst creates a massive “afterburn” effect (EPOC), where your body continues to burn calories at an elevated rate for the rest of the day.
Another effective finisher is the “Descending Distance Ladder.” Load the sled with a moderate weight. Pull it for 40 yards, rest for 30 seconds. Pull it for 30 yards, rest for 20 seconds. Pull it for 20 yards, rest for 10 seconds. Finally, pull it for 10 yards. The decreasing distance allows you to maintain a high power output even as your muscles become saturated with lactic acid. This type of training builds “mental toughness” and the ability to push through the “burn”—a hallmark of the celebrity fitness mindset.
For those looking to target the arms specifically, try the “Arm Farm Finisher.” Attach a long rope and perform 10 hand-over-hand pulls, immediately followed by 10 overhead tricep extensions using the same rope, and finish with a 20-yard “static hold walk” where you hold the sled in a mid-row position while walking backward. By the end of three rounds, your arms will have a level of vascularity and “pump” that traditional lifting simply cannot match. This is the “secret sauce” for looking lean and defined in photos or on the red carpet.
Programming the Sled Across Different Training Phases
To see continuous results like a Hollywood pro, you shouldn’t just “do the sled”—you should program it. Sled training can be adapted for different phases of your fitness journey. During a “Strength Phase,” the focus should be on “Low-Volume, High-Load.” Load the sled with 1.5 to 2 times your body weight and perform short pulls (10-15 yards) with long rest periods (2-3 minutes). This builds the raw power in your back and the “thickness” of the muscle fibers. Think of this as the foundation-building phase.
When transitioning into a “Definition or Cutting Phase,” shift the focus to “High-Volume, Low-Rest.” Reduce the weight to 50-70% of your body weight and increase the distance to 40-50 yards. Keep your rest periods under 45 seconds. This creates the metabolic demand necessary to strip away body fat. In this phase, the sled acts more like a cardiovascular tool that happens to preserve muscle mass. This is likely how Hale trains when preparing for a specific project where she needs to look her leanest.
Finally, for “Maintenance and Longevity,” use the sled as a “Finisher” at the end of your regular weightlifting sessions. Adding just 10 minutes of sled work twice a week ensures that you maintain your functional movement patterns and cardiovascular base without overtaxing your recovery. The beauty of the sled is its “autoregulatory” nature; if you’re feeling tired, you’ll naturally move the sled slower. If you’re feeling energetic, you’ll push it harder. It is one of the few pieces of equipment that truly meets you where you are on any given day, making it a sustainable, lifelong tool for a sculpted back and arms.
Frequently Asked Questions
1. Can I do sled training if I don’t have access to a turf gym?
Yes! While turf is the ideal surface for a traditional sled, you can buy “all-terrain” sleds with wheels or plastic skis that work on grass or asphalt. If you are on a budget, a “tire sled” (an old car tire with a bolt and rope attached) is a classic DIY alternative that provides excellent resistance on most outdoor surfaces. Many parks now also feature outdoor fitness equipment that may include sled-like stations.
2. How often should I perform sled workouts for the best results?
For most people, 2 to 3 times per week is the “sweet spot.” Because sled training lacks an eccentric phase, your muscles recover much faster than they would from heavy deadlifts or squats. This means you can train more frequently. However, you should still listen to your body and ensure you aren’t overtaxing your central nervous system, especially if you are also doing high-intensity cardio or other heavy lifting.
3. Is sled training better for fat loss or muscle building?
The magic of the sled is that it does both simultaneously. It is a “compound” tool. By moving a heavy object over a distance, you are performing work that requires a lot of ATP (energy), which burns calories. At the same time, the resistance provides the stimulus needed for muscle hypertrophy. It is one of the most effective tools for “body recomposition”—the process of losing fat while gaining muscle.
4. Will sled training make my arms look too bulky?
This is a common concern, but for most women, “bulk” is a result of a high-calorie surplus rather than the type of exercise. Sled training actually tends to create a very lean, “dense” muscle look rather than a puffy, bulky look. Because of the high metabolic demand, it helps keep body fat percentages low, which ensures that the muscle you build looks toned and sculpted rather than large.
5. What should I do if I find the sled too difficult to move?
If the sled feels “stuck,” check two things: the weight and the surface. Some gym turfs are “stickier” than others. Start with an empty sled to test the friction. If you are struggling with the arm movements specifically, reduce the weight and focus on the range of motion. It is better to move a lighter sled with a full, deep contraction than to struggle with a heavy sled using half-reps. Strength will come with consistency.
