This intense upper body strength workout focuses on exhausting the chest, triceps, and shoulder muscle groups. You'll completely work each muscle group before moving on to the next. Most exercises will consist of three heavy sets with a goal of 12 or fewer reps per set. After the third set you'll 'hit it' with an intense finisher set to really fire up those muscles! You'll be using heavy weights in this workout and should be going to failure on at least some of the sets in each muscle group. Intensity matters so always make sure that you are choosing a weight that challenges you!
