The leg press is a machine exercise targeting the leg muscles, including the quads, glutes, and hamstrings. It's a favorite among lifters who prefer the seated position to standing with a load on the spine. The leg press is often used as an accessory for squats or deadlifts, but can also be the main lower-body movement in a workout. It is often performed for moderate to high reps, such as 8-12 reps per set or more.
