Video: Park Bench Dipsadmin
Sit on the edge of the bench with your hands placed at your sides with palms facing down gripping the seat. Using your arms slowly raise your body up and lower (dip) it down in front of the bench a few inches (see video for correct position). Push yourself back up. Focus on using your tricep muscles (back of the arms) throughout the movement. Slowly lower yourself again and repeat exercise for 2 sets of 12.
Do not shrug your shoulders up toward your ears and do not lock elbows.
Extend or walk your legs farther out in front. For an even greater challenge alternate raising one leg at a time.
