"Squat with load" is the most complicated in bodybuilding, with many practice parts, and it is a prescribed movement in weightlifting competition. "Squat with load" has a strong stimulation to the whole lower limbs and trunk, and can exercise quadriceps femoris (rectus femoris, midthigh, lateral thigh and medial thigh), gluteus maximus, biceps femoris, semitendinosus and semimembranous muscle, and also has a strong effect on erector spinae, piriformis, adductor, gluteus medius, gluteus minimus and calf muscle. In addition, "weight-bearing squat" has a positive impact on a series of physiological and biochemical reactions such as cardiopulmonary function, nerve regulation and hormone secretion, so practicing "weight-bearing squat" can be said to be a compulsory course for professional athletes and amateur bodybuilders.
