Week 2 here we go. We are adding dumbbells to today's circuit. Choose a light to moderate weight as you will be performing a single set of each exercise, then repeating for a total of 3 rounds. Rest as needed between rounds, but no longer than 2 minutes. We are going to work your triceps, back, shoulders, and biceps. This is one of my favorite circuits for toning the upper body. It's not easy but I know you can do this!
