Triceps Dip. Start sitting with feet flat on the floor, knees bent, and hands behind hips, fingertips pointing forward, gripping on a barbell (that won't roll). Slowly bend elbows and lower body as far as possible. Squeeze triceps to straighten arms and lift body back to start (don't use your butt to help you lift).
