Muscles used

• Front deltsfront of the shoulders

Main muscleLie back on an incline bench with your arms hanging slightly behind your torso, then curl the dumbbells up. The main muscle driving this movement is your biceps. Your biceps start from a stretched position and contract to bend your elbows.

Supporting musclesYour brachialis helps bend your elbows, and your brachioradialis assists from the forearm.

How it should feelAt the bottom, your biceps should feel stretched. As you curl, the front of your upper arms should shorten and squeeze while your elbows stay slightly behind your body.

Signs you're offIf your elbows swing forward or your shoulders lift, you are using your shoulders and momentum. If your lower back lifts off the bench, your posture is breaking down.

Remember thisKeep your back on the bench, let the biceps stretch, then curl without moving your elbows forward.
