Well IMO. Those numders unless he is 4 foot 95 lbs I say keep working on building a base. Get stronger everywhere. I mean those arent that out of line look at BIG legs, ass core those are used in squat. compared to lil twigs (arms) chest, shoulder, back that is what makes a bench basically.
Keep working hard keep it simple and just work HARD, eat, recover, use a good program and that bench and all else will go up
