Modern life can be hell on your shoulders — sitting all day at a cramped desk, hunching forward to answer texts, slouching in the driver's seat on your commute home. So if you're not doing the right moves to build powerhouse deltoids (the shoulder's muscle group) during your workout, you're doing your body a major disservice.
"Strong shoulders are safe shoulders, protecting you from serious injury," says Craig Ballantyne, strength and conditioning coach and author of Turbulence Training. "Developed delts also kick up your performance in almost every major exercise and sport." Plus they improve functioning in daily life too, making everything from hauling a camping pack to picking up your kids easier. These 11 shoulder-building exercises will boost your shoulder size and strength, improve flexibility, and stave off injury.
