Set-up: Grasp an appropriately light kettlebell, and rotate until the bottom of the bell faces the ceiling.
Lift: Bracing through your core, press the weight overhead, keeping the bottom of the bell on top. Press just shy of locking your elbow at the top, then return the weight under control. Once complete, switch to the other side and repeat the prescribed repetitions.
Emphasis: Keep your core and back strong while maintaining natural spine position. Your entire body, from your legs, core and back - up through to your shoulder girdle and elbow - should work to stabilize the movement. The stabilization challenge in this exercise should not be taken for granted - be sure to choose a weight you can control.
