A versatile compound exercise ideal for targeting the major muscle groups in the lower body with reduced stress on the lower back. It's the generic leg press a drafted program references by default — "leg press" on a plan means this machine pressing pattern.
The most common variant is the angled leg press — the 45° sled where you press the weight up and away on a diagonal. If a plan just says "leg press," treat it as a free choice: use whichever leg press machine your gym has, and the rest of the program still works.
