One thing I like to get people to do is 21's on Incline Dumbbell Supination Curls - 7 reps halfway up, 7 reps halfway down, 7 full reps. The incline position will also make it difficult for you to cheat those repetitions up. Give it a go! Supination Curls are far more comfortable on the wrist, but most much more difficult on the biceps, by using the fantastic GLOBE GRIPZ™. GLOBE GRIPZ™ also allow for a bit more variety too, such as a supination positive and a pronation negative - check out the video demonstration at www.GlobeGripz.com .
