How to do One Arm Kettlebell Swing
Step 1: Begin with the kettlebell between your legs and one arm out to the side. Be careful that you do not bend too low. You don’t want to do a squat, but bend down just enough to be able to get the kettlebell between your legs.
Step 2: Swing the kettlebell up forcefully to a point between your belly button and chest. As you bring it up, emphasis should be on your core and lower body, not arms. Your arms can be straight or slightly bent.
Step 3: Let the kettlebell fall back down and repeat.
