HOW: Grab onto a kettlebell with one arm and hold it straight up overhead with the weight resting on the back of your arm. From here, lower the kettlebell as you bend your elbow at your side. When the weight gets just above your shoulder, press it back up to the starting position.
FEEL: You should feel your shoulder muscles working.
COMPENSATION: Keep your back upright, don’t arch it. Make sure your arm lowers the weight at your side, not out in front.
