Sexy shoulders and lean arms aren't going to appear out of thin air, although that would be pretty awesome if that were possible. If you want leaner arms, this four-move, four-minute workout created by SLT founder Amanda Freeman will have your arms shaking once you're done! Here's how to do it.
Holding light weights (or equally weighted objects) in each hand, start with hands at waist level and slowly (use a 4-count) lift up and away until your arms are extended at shoulder height.
Lie face down on a mat with light weights in hand. Engage your core and lift your legs up off the mat.
Start the movement with arms straight by your side and slowly extend arms out and forward like you're swimming the breast stroke and then bring them back to your sides.
