If you're looking for a 30 minute arm workout that'll help you go sleeveless in confidence, this is for you. Whenever I'm working with a new client, trying to boost someone's confidence I recommend arm workouts. I find that exercising the arms gets noticeable results faster compared to other parts of the body... specifically when they're long enough (30 minutes long to be exact) and focus on the biceps and other secondary arm muscles. Doing 30 minute arm workouts targeted this way helps define the arms, build lean muscle, and burn fat... so you can see and feel results quickly.
