Most people hold the kettlebell in the middle of the handle. That's the wrong way and the least safe — it takes the wrist out of a stacked, stable position.
Hold the kettlebell on the corner of the handle, not the middle. True for swings, cleans, and getting the bell overhead.
Holding the bell with a bent-back wrist overhead kills the wrist, elbow, and shoulder — and you wind up leaning way too far back.
For ANY kettlebell overhead movement — snatch, press, get-up — keep the knuckles pointed directly at the ceiling. Turn THIS into THIS.
These two fixes save you from injuring your wrist, shoulder, and back — the classic kettlebell overhead failure points.
