1. Strap on an arm blaster device around your neck so it rests against your abdomen and pins your upper arms.
2. Hold a dumbbell in each hand with a supinated grip, arms extended.
3. Curl both dumbbells upward toward your shoulders, keeping upper arms pressed against the blaster.
4. Squeeze the biceps at the top, then slowly lower back to full extension.
