avoid isometric biceps holds for growth
Mike explicitly calls out the clip of Ben doing a biceps hold with 300 lbs as sarcasm, warning that it's dangerous and ineffective. He instead recommends traditional bicep curls and pulling exercises. This aligns with his general stance that dynamic movements are superior. The risk of joint injury in such an unorthodox position outweighs any potential minimal growth.
The isometric position doesn't allow for meaningful overload across full ROM and places awkward stress on elbows/shoulders.
The probability of injury is high. The probability that you summit enough tension to your biceps to get bigger notably is low. Just do bicep curls and all kinds of different pulling exercises. Don't do that.
