The arms are notoriously difficult to sculpt. (You didn't think it was going to be easy, did you?) The problem: Most traditional workouts focus on the biceps and triceps. Instead, to get your arms in great shape for tank-top season and keep them looking amazing throughout your life, you need to do three things: use dynamic movements, recruit your chest and upper-back muscles and work those arms to exhaustion. This trifecta of strategies will totally trim and tone you from wrist to shoulderand have you waving bye-bye to flimsy arms (and bat wings!) for good.
Most of these exercises involve punching. This move requires you to work against your core as you extend your arm out, while also challenging your back and shouldersplus, all those quick, constant movements engage your brain to ensure you aren't just mindlessly going through the motions. Do this series six days a week, and remember to add in 30 to 60 minutes of cardio.
Do the sequence twice, switching arms the second time through moves 3 and 4.
