15 Day Squat Challenge

Squats are one of the best ways to strengthen your hips, abs, quads, and hamstrings. Even better, you can do them anywhere, anytime. The challenge consists of 5 exercises that make up a single set. You'll start slowly, completing a total of 25 repetitions, gradually increasing to a maximum of 150 repetitions on day 15. No equipment is needed. However, if you want to increase the intensity, you can add free weights or a resistance band around your thighs. If the exercise is too difficult, you can use a wall or chair for support.
