The leg flexion is a basic isolating exercise that targets two main muscle groups: the calf muscles (calf and flounder muscles)and the hamstrings (biceps femoris, semiteminosus, and semiteminosus).

Leg bends are performed on a gymnastic bench with a lifting crossbar. The classic version of the exercise is performed lying on your stomach, tucking your ankles under a soft roller.

The hip flexor muscles are several muscles that bring the legs and torso together in a flexor motion. They allow you to raise your leg or knee to the torso, as well as bend the torso forward to the hip. You can stretch or tear the hip flexor muscles due to sudden movements or falls.
