how about superset like dumbell curls and concetration curls does that makes sense
I remember reading an article where Darrem Charles did this to shock his biceps. You can superset any movements with the intention of pumping the muscle full of blood. You use less weight usually but you can get a workout done quicker, which some feel is important. A good combo that I have used at times is a curling movement and chins, focusing on the bicep contraction. For triceps this could be any movement followed up with pushups or bench dips, which Lee Priest has been seen doing from time to time.
Arnold used to superset biceps and triceps 2-3 times a week precontest. I prefer this method when using arms but have tried supersetting the same muscle group exercises, to achieve that antagonistic muscle effect which really pumps the muscles up.
