Tighten Your Triceps With These Moves

• Stand with your feet hip distance apart.
• Hold one dumbbell (go for your heavier weight) with both hands, bending the elbows behind your head.
• Straighten your arms to lift the dumbbell into the air, and then slowly bend the arms to lower. This counts as one rep.

This exercise is similar to the skull crusher, but by standing you will be working your core more.
