The biceps are a pair of muscles located at the front of the upper arm. They play a crucial role in bending the elbow and rotating the forearm. When you lift something heavy or perform activities like curling weights, your biceps are actively engaged, helping to pull the forearm up towards the shoulder. In addition to their functional importance, well-defined biceps are often seen as a symbol of strength and fitness. Many people work on building their biceps through exercises like bicep curls and pull-ups. Strong biceps not only enhance physical appearance but also improve overall arm strength and functionality.
