Today we have three simple moves for those shoulders and arms meant to build stunning posture and definition. All you need is a theraband. It's important to remember alignment is everything. So set yourself up by standing or sitting tall, engaging your core muscles (abs, pelvic floor, shoulder girdle). The trickiest part is keeping your shoulder blades sliding down and connected to your back. You don't want to feel this in your neck. If at any point you're not able to maintain your alignment and core connection, then slow it down, decrease your range of motion, or try it with a lighter band. 8-12 of each of these should be just right with a light to medium resistance band. Repeat for more of a challenge.
