@jo_domiaty_champion: Dumbbells spider curl alternating. The alternating dumbbell spider curl is a variation of the traditional spider curl that focuses on isolating the biceps while allowing for unilateral movement. This exercise not only targets the biceps brachii but also engages the brachialis and brachioradialis muscles #CapCut #bodybuilding #gym #Fitness #bicep #biceps #bicepscurls
