Ultimate Arm Exercise: Using a light weight (8 lb. dumbells pictured) start at picture 1. Think: Down, Up, In, Out, Down, while doing this exercise. Do 12-15 repetitions per set, 3 sets total. If you find by rep 10, you can't keep your form and hit your rep, lower the weight. If you're not challenged at rep 15, up the weight. Add this to your workout, once a week, and you'll see a big change!
