Sled One Leg Hack Squat
Master the Sled One Leg Hack Squat to build powerful quadriceps and improve unilateral strength.
Description
A single-leg variation of the hack squat performed on a sled machine, focusing primarily on the quadriceps.
How to Do Sled One Leg Hack Squat
- 1Setup
Load the sled with an appropriate weight and position yourself facing the machine with one foot placed firmly on the sled platform.
- 2Setup
Place your working foot slightly forward on the sled platform, ensuring your heel is planted and toes are pointing slightly out. Secure your shoulders under the pads and grasp the handles.
- 3
Release the safety stoppers and slowly lower the sled by bending your knee and hip, keeping your torso upright and core braced. Descend until your working thigh is parallel to the platform or slightly below, maintaining control.
- 4
Drive through your heel and midfoot to extend your knee and hip, pushing the sled back to the starting position. Exhale as you push up, focusing on contracting your quadriceps.
- 5
Fully extend your leg without locking your knee at the top, maintaining constant tension on the working muscle before initiating the next repetition.
Tips
- Maintain a stable core throughout the movement to prevent your hips from shifting and to protect your lower back from strain.
- Control the eccentric (lowering) phase of the squat, taking 2-3 seconds to descend, to maximize muscle time under tension and improve strength gains.
- Focus on driving through your heel and midfoot to engage the glutes and hamstrings more effectively, rather than pushing predominantly through your toes.
- Keep your non-working leg bent and slightly off the platform or lightly touching for balance, but avoid using it to assist in the movement.
Common Mistakes
- ×Using excessive weight causes loss of balance or rounding of the back; reduce the weight to allow for controlled movement and proper form.
- ×Not going deep enough reduces the range of motion and muscle activation; ensure your working thigh reaches at least parallel to the platform.
- ×Allowing the knee to cave inward (valgus collapse) puts undue stress on the knee joint; actively push your knee slightly outward in line with your toes throughout the movement.
