Here's a simple exercise for the legs. Bodyweight squats target the greater muscles of the hip and thigh (gluteus, quadriceps, hamstrings). To begin, place your feet shoulder width apart or slightly wider. Your toes should be pointed slightly outward. Next, squat down until your thighs are parallel to the floor. Be sure to keep a straight posture as you squat. Finally, return to the standing position and repeat the exercise. You should exhale as you stand up. Be sure to perform the squat slowly and with control. Do not bounce out of the squat position. If needed, you can extend your arms out in front of you as it will help with balance.
