Instead of placing both feet flat on the platform, you rotate your body so your torso faces sideways and your working leg presses through the plate along a lateral path. This changes the line of force from a straight vertical push into a push that travels through your hip from the side, which is why the inner thigh and hip musculature do far more work here than in a standard two-leg press. The main benefit of this setup is that it loads the adductors and hip stabilizers through a long, supported range. Muscles on the inside of the thigh are hard to train with heavy resistance using free weights, and most adductor work is done with light cables or machines in a seated position. On the sled you can gradually load the movement with plates, making it useful for lifters who want stronger hips for squats and deadlifts, field athletes who cut and change direction, and anyone rehabbing or strengthening around the groin area in a controlled way. Because you sit sideways on the seat with one leg extended toward the plate, your body has to hold itself in place through the trunk and the non-working leg. The hand grips and the seat pad give you the anchoring you need, but you still have to stay tight through your core so the press comes from the hip and thigh rather than from twisting your torso into the sled. Execution is straightforward once the position clicks: place the working foot on the plate, extend the leg so the sled unlocks, then press out and control the sled back until the knee travels back toward you without your hip rolling forward. The leg moves in a plane roughly parallel to the floor rather than up and down, so the knee and hip track sideways together. Depth is determined by how far the knee bends toward your chest before the low back or pelvis starts to shift. Common use cases include accessory work after squats or presses, unilateral leg days where you want balanced left-to-right hip strength, and programs aimed at groin resilience for sports like soccer, hockey, and football. Because each leg works alone, weaker sides cannot hide behind the stronger one, and you can match volume side to side simply by counting reps. Safety comes down to respecting the setup. Load conservatively the first few sessions, since the adductors are often unprepared for sled-level loads in this plane. Keep a soft bend rather than slamming into full extension at the top, never place your hand near the moving sled path, and always engage the safety stops or keep the sled within its travel range before releasing pressure. ## Instructions 1. Sit sideways on the sled machine so your torso faces along the length of the seat, and grip the side handles firmly with both hands. 2. Place the foot of your working leg flat in the center of the plate, then slide your hips back against the seat pad so your trunk stays vertical and stacked. 3. Bend the non-working leg out of the way, hooking it behind or bracing it against the seat so it does not interfere with the sled path. 4. Brace your core and press the sled slightly upward to take the weight off the safety locks before beginning the set. 5. Press through the whole foot, extending the hip and knee together so the sled travels out along its rails in a straight line away from your body. 6. Stop just short of full knee lockout at the end of the press, keeping tension in the thigh and hip instead of resting at the top. 7. Control the sled back until the knee bends and the sled returns near your torso, letting the inner thigh and hip take the load through the full range. 8. Exhale as you press out, and inhale slowly as the sled comes back toward you. 9. Complete all repetitions on one leg, then reposition and repeat the exact same setup and rep count on the opposite side. 10. Re-engage the safety stops or fully return the sled to its resting position before letting go of the handles and getting off the machine. ## Tips & Tricks - The most common mistake is letting the pelvis roll toward the sled as the weight returns, which turns the exercise into a torso twist. Anchor your lower back against the seat and let the hip joint do the hinging. - Keep the working foot flat on the plate throughout. Pointing the toes up or rolling onto the outside of the foot shifts stress into the knee and tells you the load is too heavy. - Start noticeably lighter than your normal leg press weight. The inner thigh works in a plane it rarely sees at heavy loads, and going too heavy too soon is the fastest way to strain the groin. - Do not chase extra depth by letting the knee drift toward your armpit. Stop the descent once your pelvis would have to move, and gradually increase range over weeks. - Keep a small bend in the knee at the top of every rep. Snapping into full lockout with the sled loaded transfers force into the joint instead of the muscle. - Grip the handles hard for the entire set. Many people lose their torso position mid-set because their grip relaxes, and everything downstream from there gets sloppy. - Match sides exactly. Do the weaker leg first, then repeat the same rep count and load on the stronger side rather than letting one side do more total work. - If your hamstring cramps on the non-working side from holding it suspended, rest that foot lightly against the seat frame rather than letting it dangle. - Warm up the hips with a few bodyweight lateral leg swings before your first set, since cold adductors in this position are quick to complain. ## Frequently Asked Questions ### What muscles does the Sled Side Leg Press work? The primary work comes from the adductors along the inner thigh, with strong support from the glutes and quads as the leg extends. The trunk also works isometrically to keep your torso from rotating toward the sled. ### How is the Sled Side Leg Press different from a regular leg press? A regular leg press uses both feet on the plate and drives the sled in a straight up-and-down path, loading the quads and glutes evenly. The side version places you sideways on the seat with one leg pressing along a lateral path, which shifts the emphasis to the adductors and hip stabilizers. ### Can beginners use the Sled Side Leg Press? Yes, as long as they start with very light plates and focus on keeping the torso still. The machine supports the body well, but beginners should master the hip position with minimal load before adding weight. ### Why do I feel the Sled Side Leg Press in my groin? That is the intended target. The adductors run along the inner thigh and cross the hip, and because the leg presses out sideways against the sled, they lengthen and shorten under load throughout each rep. Mild muscle soreness is normal; sharp pain near the groin is a signal to reduce the load and range. ### How heavy should I go on the Sled Side Leg Press? Start with roughly a third to half of what you would use on a two-leg leg press and build from there. Because the adductors are usually less conditioned for heavy loading in this plane, progress gradually week to week. ### Should both feet touch the plate during this exercise? No. Only the working foot stays flat on the plate while the other leg is drawn back and braced against the seat. Having the trail leg on the plate would turn the movement back into a standard press and defeat the purpose of the side position. ### What is the most common mistake with the Sled Side Leg Press? Rotating the hips and torso toward the sled as the weight comes back in. Fix it by keeping your back pinned to the seat pad and gripping the handles hard so the only moving joints are the working hip and knee. ### What can I substitute if my gym has no sled machine? A cable adduction exercise with an ankle strap, a seated adductor machine, or side-lying leg raises with a band cover similar ground. They will not allow the same heavy loading, but they train the same inner thigh and hip region. ### Is it safe to do the Sled Side Leg Press after a groin strain? It can be a useful progressive loading tool because the sled controls the path and the resistance is adjustable, but return-to-training decisions after an injury should come from a qualified professional who has assessed you directly. ### Where should the Sled Side Leg Press fit in my workout? Treat it as an accessory movement after your main squat or press work. Two to three sets of moderate reps per side is enough, since the adductors also assist in many other lower body exercises you perform in the same session.
