I am not a sports scientist. It feels like like, as the kettlebell comes to rest in the rack position, that I am "coiled" and I can then "uncoil" that tension or energy or whatever you'd like to call it to make my press better, stronger than it would be without the clean. I feel fairly certain that someone, somewhere has quantified this, but I don't have a link to a study and I still haven't had a chance to look for a reference in ETK. If I have caused any confusion by my use of the word energy when perhaps I should have said tension, I apologize. But when you pull back on the bow in preparation for shooting the arrow, are you storing energy or tension? Whatever that is, the clean feels like that to me, and as others here have said in their replies on this thread, I think we all seem to be feeling the same thing.
@Stefan Olsson, it was a good question you asked - thank you for asking it.
