Legs form the basis of your body, all the power you exert starts in your legs. With compound exercises you train over multiple joints. With a leg press you use your ankles, knees and hip joints. With isolation exercises you train over one joint and you can concentrate completely on that one muscle. This is very suitable for rehabilitation training as well as for mass training. Large muscles that you can train with leg trainers are: M. triceps surea, M. quadriceps femoris, M. hamstring femoris and the M. gluteus maximus.
The leg press is often used as an alternative to the squat. Compared to the squat, the advantage is that experienced athletes can train with heavier weights. After all, the weight does not have to be carried on the shoulders.
