The hip flexors are various muscles that connect the legs and torso during flexion . They allow you to lift one leg or knee towards your torso, as well as lean your torso forward at the hips. You can stretch or tear your hip flexor muscles with sudden movements or falls.
Anatomy and function
Bending is a bending movement that reduces the angle between two parts of the body. When the flexor muscle contracts, it brings two bones closer together, usually bending at the joint.
In the case of hip flexors, they bring the bones of the leg and the bones of the hip or spine closer to the hip joint. If the hips are already flexed, such as when sitting, these muscles do not work.
