Leg Press
The leg press is not a squat replacement, but it is a legitimate tool — it lets you push the quads and glutes hard when the squat is limited by upper-body fatigue, injury, or just needs a break.

The movement
The leg press loads the lower body through a sled that travels on a fixed track. Because the torso is braced against a pad, the spinal extensors and upper back are largely removed from the equation — all the loading lands on the quads, glutes, and hamstrings. This is either an advantage or a disadvantage depending on your goal.
Foot position changes where the stress goes. Feet placed high and wide recruit the glutes and hamstrings more. Feet placed lower and narrower shift the emphasis to the quads. Neither position is better for everyone — use foot placement as a tool to address whatever weakness or emphasis applies to your current training block.
Depth is where the leg press gets misused. Pressing with only a few inches of travel and a mountain of plates looks impressive but trains nothing through range. Bring the sled down until the knees are at or past 90 degrees, with the lower back staying flat against the pad. If the hips are lifting off the pad, the weight is too heavy or the range is too deep for your hip mobility.
LiftProof programs leg press as a quad accessory after the squat or deadlift. Log it as a lower body pushing movement. Because the movement is machine-guided, small load jumps are possible every session — aim for at least two progressive sessions before adding weight.
Technique
Form cues
- Keep the lower back flat against the pad through the entire rep
- Drive through the full foot — not just the toes
- Control the sled on the way down; do not let it free-fall
- Stop short of locking out the knees at the top
- Breathe in on the way down, out on the push
Avoid
Common mistakes
- Partial range — pride in the weight means nothing if the knees only bend 20 degrees
- Lower back rounding at the bottom — reduce the range or the weight until the back stays flat
- Feet too low — places excessive shear on the knee; move them up if knees track past toes significantly
- Unlocking the safeties before getting positioned — always set foot position with the sled locked
