Please READ and FOLLOW! When it comes to targeting the biceps, the positioning of your arms can play a significant role in engaging different muscle heads. The biceps muscle is composed of two primary heads: the long head and the short head. If your arms are positioned behind your body, such as during exercises like incline curls, the main muscle being targeted is the long head of the biceps. When you perform exercises with your arms behind your body, it places a greater emphasis on the stretch and contraction of the long head, helping to develop the outer portion of your biceps. On the other hand, if your arms are in front of your body it targetes the short head of the biceps. The short head is located on the inner side of the upper arm and contributes to the overall thickness and size of the biceps. Understanding how arm position influences the targeting of the biceps heads can be valuable in designing a well-rounded workout routine. Clarification: the percentages are just an approximate representation of muscle activation. #biceps #longhead #bench #shorthead #arms #fypp #alaska #bicepsworkout #strengthtraining #gym #wegojim #gym
