The differences between a relaxed and contracted bicep in weightlifting involve length, tension, and force generation.
Difference 1: When the bicep is relaxed, it is elongated and less tense, whereas when it is contracted during weightlifting, it shortens and becomes more taut, showcasing its bulk.
Difference 2: In a relaxed state, the bicep exerts minimal force, but when contracted, especially during weightlifting, it generates significant force to lift the weights.
