• This exercise helps develop the overall size and strength of the biceps.
• This exercise helps address any muscle imbalances between both arms with its unilateral setup.

• If not correctly executed, this exercise can injure the lower back, elbows, and shoulders.
• This exercise can also hurt your wrist.
• Proper execution and progression of resistance are a must to avoid injuries.
• Beginners should always start with light resistance and practice good form first.
