Fix Short Extension in the Snatch & Clean
If you have trouble extending completely in the snatch or clean, here’s a drill for you.
First feel the position we want—Keeping the legs vertical and the trunk rigid, tighten your glutes to bring the shoulders behind the hips. Imagine stretching the upper body up and back rather than simply hinging backward.
Next, perform a set of hang deadlifts to this simulated finish position. Make sure your legs are vertical instead of pushing the hips forward.
Finally, perform a complex of 2-3 hang deadlifts to the simulated finish position + 1 hang snatch or clean trying to replicate the finish position you’ve practiced, and progress to the same sequence from the floor.
