Start with feet together and arms by sides. Bend at elbows (but keep them close to body) to bring forearms wide and up to hip height. Begin making small circles with both forearms in a forward motion while simultaneously taking quick hops with feet. (If you’re using a jump rope, the goal is to revolve the cord around body and clear it under feet with every hop.) One jump equals one rep.¬†Perform 20 reps, then immediately continue on to your next move (you’re doing six to eight total). When you’ve completed all of your exercises, rest for 30 seconds to one minute. Then, repeat twice more for a total of three rounds
