Whole Body Vibration... Why Doesn't Dave Like Side-To-Side Oscillation?
Dave mentions that he likes the up and down WBV plates v. the more common side to side ones as an aside here:
"There are a few mass-market ones with a history of weak welds or cheap (but unhealthy) side-to-side rocking motion."
Why? What about the expensive side-to-side rocking ones? There's one of those at my gym, and internet research seems to suggest that's more healthy.
