Leg Press
Heavy leg work with the spine fully supported — brutal and safe is a rare combo.
Setup
- Feet mid-platform, hip-width.
- Back and hips glued to the pad.
How To Do It
- Lower until knees near 90° or hips start to curl — stop there.
- Press through the whole foot, never locking knees hard.
Breathing
Inhale down, exhale press.
Common Mistakes
- Butt curling off the pad at the bottom — shorten the range.
- Knee slam-locking at the top — soft finish.
Programming It
Three to four sets of 8-15. The supported back means you can push closer to failure than on a squat.
Why This Exercise Works
The leg press removes the trunk from the equation. Your back is supported, so the limit is what the quads and glutes can push rather than what your spine can stabilise. That makes it the honest choice when the legs still have work left but the lower back is finished — and a poor choice if you are using it to avoid learning to squat.
Where You Should Feel It
Quads and glutes, with the back supported so you can push much closer to failure than on a squat. Lower back rounding at the bottom means the sled has come down further than your hips allow.
Where It Fits in a Program
Heavy leg work with the spine fully supported — brutal and safe is a rare combo. Programme it early, while you can still execute it well.
Progressing and Regressing It
To progress the leg press: add a plate, or slow the eccentric to three seconds. To regress it: reduce the range to what the lower back tolerates without rounding.
Who It's For
Anyone wanting leg volume without spinal load, and anyone whose squat is limited by their back. Do not chase depth by letting the pelvis tuck.
Equipment and Substitutions
As written here it uses a leg press machine. The machine buys you stability, not a different muscle. Anything below that loads the same direction will build the same thing.

Common Questions
What muscles does the leg press work?
The leg press primarily trains the quads, glutes.
How many sets and reps should I do?
Three to four sets of 8-15. The supported back means you can push closer to failure than on a squat.
What are the most common leg press mistakes?
Most often: butt curling off the pad at the bottom; knee slam-locking at the top.
Do I need a leg press machine to do this?
This version uses a leg press machine, and it trains the quads, glutes. A free-weight substitute from the list works, but you will need to control the path yourself — expect a lighter load for the same effort.
Is this safe if I have an existing injury?
The leg press loads the knee and ankle, so stiff ankles or an irritable knee will show up early. Sharp pain at a single point is the one to stop for; a general burn is not. Not medical advice.
