Squats are a core exercise which works many muscle groups at the same time; legs, butt and back mostly but also stabilizing muscles in arms and torso. Unaided squats with free weights cause your body to do the most work but can be dangerous. Most people use a rail type squat rack that stabilizes the weights for you and gives you a way out if you can't bring the weight back up.
