What It Is
Builds leg strength with your back supported and no bar to balance. You can safely push more weight than a squat allows.
How to Do It
Set the seat so your knees start bent to about 90 degrees. Place your feet shoulder-width apart on the platform. Push it away until your legs are almost straight, then lower it slowly. Stop lowering before your hips curl up off the seat.
Skill Level
Beginner. One new pattern or machine to learn, with light loads and low risk.
Type
Strength. Builds muscle and strength with controlled, resisted movement.
Engagement
Bilateral. Each rep works both sides of the body at once.
