Dumbbell Drag Curl
1) Stand tall with the chest up, core tight, head neutral and back flat.
2) Grab the dumbbells with the palms facing up (underhand grip).
1) Keep the weights close to your body as you drag them up towards your shoulders. As you do this, the elbows will point behind you.
2) Pause at the top. Now, slowly lower them back down to the starting position.
