Key Coaching Points
Starting with the kettlebell between the legs, pull the bell between your legs as if snapping a football.
You should be in a hip hinge position and feel your hamstrings are stretched
Forcefully extend the hips to accelerate the bell (key words: fire your hips).
Keeping the arms straight, you should notice the point at the top of the movement where the bell becomes weightless (squeeze glutes together at top).
From the weightless point of the movement, guide the bell down as though absorbing it.
Do not raise bell using your deltoids.
Note: this is one version of the swing. One could also limit the acceleration of the bell by extending the shoulders (keeping the bell close to the body)
