Wall balls are a dynamic full-body exercise that combines a squat with a medicine ball throw. To perform this exercise, stand facing a wall at arm's length with your feet shoulder-width apart. Hold a medicine ball at chest level with both hands. Begin by squatting down, keeping your chest up and your back straight. As you rise from the squat, use the momentum to throw the ball up against the wall, aiming for a target height (usually around 8-10 feet). Catch the ball as it comes back down and immediately transition into the next squat. This exercise requires coordination, timing, and power, engaging multiple muscle groups simultaneously.
