Squats: Squats target the quadriceps, hamstrings, and glutes. Stand with your feet hip-width apart, lower your hips as if sitting back into a chair, and then return to standing. You can do bodyweight squats or add weights for more resistance.
Lunges: Lunges work the quadriceps, hamstrings, and glutes. Take a step forward or backward, bend both knees to lower your body, and then push back up. You can do stationary lunges or walking lunges.
