So me and my roommate got into an argument the other day about isolation workouts. Basically, we both bench but he also works out his separate muscles like doing bicep curls. I told him that biceps will grow as your bench increases (neighboring muscles must grow). Keep in mind that I am following Pavel's book "Power to the people", so I am also doing deadlifts. Are biceps really that useful in MMA? Should I be doing isolation exercises or is that just a waste of time? Please share some insights if you have experience.
