Setup
- 01Set the shoulder pads so the back stays flat against the pad.
- 02Place feet around shoulder width on the platform.
- 03Brace the trunk and unlock the safety catches.
- 04Take a breath and hold the sled before descending.
Execution
- 01Bend the knees and lower the sled under control.
- 02Keep heels down and knees tracking over the toes.
- 03Descend until the hips drop and depth is controlled.
- 04Press through the whole foot to extend back near lockout.
Checkpoints
- -The back stays flat on the pad throughout.
- -Heels stay planted on the platform.
- -Knees track in line with the toes.
- -Depth is consistent across every rep.
Common mistakes
- -Letting the heels lift as depth increases.
- -Allowing the knees to cave inward under load.
- -Bouncing out of the bottom instead of controlling it.
- -Slamming the knees into a hard lockout at the top.
Programming notes
- -Use 3 to 4 sets of 8 to 15 reps.
- -The supported back makes it a strong quad builder when squats are fatiguing.
- -Foot placement shifts emphasis but should never sacrifice knee tracking.
