There are many ways to exercise leg muscles, and the training method is usually determined by the level of muscle strength. Unassisted plyometrics can be performed up to muscle strength level 3, and active anti-gravity or resistance plyometrics are performed at level 3 or above. Leg muscles can be followed in different parts of the body: (1) Quadriceps exercises: there are barbell squats, dumbbell squats, leg raises, seated leg bends, lunges, and bent leg hard pulls. (2) Hamstrings are worked: bent-over leg bends, seated reverse leg bends, high leg raises, and straight leg hard pulls. (3) Tibialis anterior and tibialis posterior muscle groups: seated heel raises, standing heel raises and ankle weighted plantar flexion. Meanwhile, attention should be paid to leg stretching before and after exercise to prevent muscle strain. Patients are advised to perform muscle exercises under the professional guidance of professional therapists and fitness personnel to prevent sports injuries.
