Squats are a popular strength training exercise that primarily targets the muscles in the lower body, including the quadriceps, hamstrings, and glutes. To perform a squat, stand with your feet shoulder-width apart, then bend your knees and lower your body as if sitting back into a chair. Keep your chest up and back straight, and ensure your knees do not extend past your toes. Squats can be done with just your body weight or with added resistance, such as dumbbells or a barbell. They are beneficial for improving overall strength, balance, and flexibility, making them a staple in many fitness routines.
