This is an excellent finisher to your tricep workout. Hold barbell palms toward your feet, thumbs and fingers on the same side. If you don't have a barbell, you can perform the exercise with dumbbells held horizontally. Press the small of your back into the bench, tipping pelvis under. Abs tight. Keeping the elbows directly over the shoulders, in a fixed position - elbows act as a pivot only, they don't move forward or backward. Slowly lower bar to your forehead. Exhale as your press the weight back up. Keep on flexing!
