All,
Camron's video illustrates a great point ... you can perform the swing without really performing the swing. I mean, you're doing it, objectively, but you're not doing it, subjectively - a trained eye can see the difference. And, as an aside, this is why the hardstyle swing can't be a crossfit exercise, for example - there is no objective way to judge tension - the whole point of the swing.
Most people are either swinging too light, and/or are swinging with a lot of looseness. In 1-h swings, you should literally be feeling the soft tissue strain down your back from your shoulder to your pelvis in an attempt to arrest the bell's descent on the bottom, and the ascent at the top. In the 2-h swing version, this feeling is there but not so prominent - 2 hands on the bell and all.
You don't NEED ring work ... you don't NEED batwings ... not that these are not great ways to work scap retraction, but, you just need a heavier bell AND get TIGHT against it - swing "correctly". This cannot be overstated enough ...
One more time, for sh*ts & giggles:
