In the online videos, the athletes stagger their feet, in the Pro+ video it seems as though they are not (I'm not super obsessive in looking at their form as I follow-along). When I stagger my feet the noisiness of my shoulder is decreased, when I bring my feet close together or side by side the noisiness returns. I'm wondering as to which way is preferred. Given that staggering my feet ends up being pain-free. I'm going to stick with that for now. If it turns out that my feet have to be side by side for mastery then I'll slowly works towards that. Step 8, here I come.
Cheers.
