Our shoulder muscles usually aren't ones to be talked about. They aren't the "pretty", muscles others praise and admire. Usually everyone is all about biceps, abdominals and booty; but I'm here to tell you that strengthening you shoulders is just as sexy and important as strengthening the others. Strong shoulders not only look great in anything and everything you wear, they are also important for your overall strength in your arms.
Try this circuit 3x around doing 10-12 repetitions each round.
Your shoulders are sure to burn.
You will thank me in a few weeks when you start to see new definition where there wasn't any before.
