One machine that I rarely use in the gym is the leg press. It is often in use by others but the main reason I shy away from it is because I wasn’t exactly sure about the proper way to use it. With that being said, I looked up videos on how to use one and found a really good explanation below.
All machines in the gym can cause injury if you don’t know what you’re doing but specific ones such as the leg press machine can also cause lower back injuries if used improperly. Of course, watching a video helps but if you are having doubts, ask a personal trainer to go over it quickly with you.
