hrm... my 2 cents
branches - reverse grip curls (ez bar for my wrists)
biceps - rope curl / preacher curl
triceps - tricep extension ^ bar
triceps - dips (parallel)
triceps - reverse grip tricep pulldown "W" bar underhand grip
but i've never cut before, so i don't know how you'd do sets for them for cutting. the last tricep exercise will really beat your triceps to a pulp. the DOMS will kill you if you've never done them before.
