Sit on the leg press machine, back firmly against the pad. Position feet wider than shoulder-width, toes slightly outward. Grip handles for stability. Unlock the platform, lower legs to a 90-degree angle (or slightly deeper), ensuring knees track over toes. Extend legs by pushing through your heels, avoiding full knee extension. Repeat.
Maintain a flat back. Ensure knees track over toes. Avoid locking knees. Push through heels to engage glutes and hamstrings. Control the lowering phase.
