Not only will squats shape your quads, hamstrings, and glutes, they'll also help your balance and mobility, and increase your strength.
Squatting exercises are particularly beneficial for sports where explosiveness is important (running, sprinting, tennis, etc.) because it specifically exercises the muscles that support your weight (lower limbs) and make the body move.
