How to do Dumbbell bicep curls
Begin standing with the feet hip distance apart and hold a dumbbell in each hand with a supinated grip (palms facing forward) and elbows straight. Have a tall posture with shoulders back.
While keeping the elbows near your side and upper arms stationary, raise the dumbbells up toward your shoulders.
Then, lower the dumbbells back down to the start position with control.
Repeat for the desired repetitions.
