A squat is a strength training exercise that primarily targets the muscles in the lower body, including the quadriceps, hamstrings, and glutes. It involves bending the knees and lowering the body as if sitting back into a chair, then returning to a standing position. Squats can be performed with body weight or added resistance, such as dumbbells or a barbell. Squats are beneficial for improving overall strength, stability, and mobility. They can enhance athletic performance and support daily activities like walking and climbing stairs. Proper form is essential to prevent injury and maximize effectiveness during the exercise.
