The Smith machine leg press is a machine-based movement that targets the quads, glutes, and hamstrings. It can serve as a substitute for the leg press or be programmed similarly to the leg press. It is usually performed for moderate to high reps, such as 8-12 reps per set or more, as part of lower-body training. If your Smith machine has safety bars, set them at a height that allows you a full range of motion while giving adequate protection from the weight potentially falling.
Hammers the quads, glutes, and hammies
Effective for high-rep leg training with light to moderate weights
The bar moves on a track making it easier to control
Position a Smith machine bar a couple feet off of the ground. Ensure that it is resting on the safeties. After loading the bar to an appropriate weight, lie underneath the bar. Place the middle of your feet on the bar, tucking your knees to your chest. This will be your starting position.
Begin the movement by driving through your feet to move the bar upward, extending the hips and knees. Do not lock out your knees.
At the top of the motion, pause briefly before returning to the starting position.
