Most people just do barbell/dumbell curls and call it a day 😪but your biceps deserve more. The biceps have 2 heads → short head (inside) and long head (outside). Both bend the elbow but they respond differently based on shoulder position. That’s why mixing up your angles matters if you want big round arms instead of flat ones. My favorite picks 👇 ✅ Dumbbell preacher curls ✅ Uni dumbbell preacher curls ✅ Rope hammer curls Hit your biceps through different positions and watch them actually grow.
