@Butch, our clean is based on our swing, and our swing's basic motion is trying to throw the bell across the room in front of you - but you hang onto it instead and it carves and arc in the air, ending up about belly or chest height in front of you.use the heels when doing cleans or snatches?
What's the Strong First way?
We drive the heels into the ground for cleans and snatches to explosively extend the hips. It's about power production. Heel lifting (not to mention shoulder shrugging) often comes from practicing barbell cleans and snatches so it can take time to change the patterning. I clarify with my students kettlebell cleans and kettlebell snatches vs barbell cleans and barbell snatches.
