This exercise will sculpt your arms and strengthen your core. Use dumbbells with handles that are raised high enough so that your knuckles don't rub against the ground.
- Start in full push-up position (legs extended behind you, abs engaged, back flat), with a dumbbell in each hand, palms facing each other, hands directly under shoulders.
- Bend elbows, keeping arms by sides, lowering chest toward floor.
- Extend arms to return to start.
