the question of who is bigger comes down to which competition. they alternate. sometimes one is bigger and sometimes the other is bigger. speaking of biceps, chest, shoulders and calves Ruhl is bigger. Triceps, back, thighs, Coleman. Everyone knows Ronnie wins because he has more detail. It will be interesting to see who is bigger this coming Olympia. Ruhl is doing a show one week prior to the O to qualify. I'm sure he will.
