Sit on the edge of a bench or chair with your hands gripping the edge next to your hips. Slide your butt off the front of the bench with your legs extended in front of you. Keep your back close to the bench and your elbows slightly bent. Lower your body by bending your elbows until your upper arms are parallel to the floor. Push yourself back up to the starting position by straightening your arms. Repeat for the desired number of repetitions.
