If there’s one exercise that has the ability to challenge most of the muscles in your body, it’s the squat.
The obvious muscles targeted are in the lower body, but in order to do this compound exercise correctly, you also need to use several muscles above your waist.
The lower muscles targeted in a squat include your:
gluteus maximus, minimus, and medius (buttocks)
quadriceps (front of the thigh)
hamstrings (back of the thigh)
