I like David! I didn’t know he made it but love his attitude!

Whats the difference between push up with the ball up or down ?

Is the bosu ball safer than a gym ball. As in does it have less chance to burst

You could also throw it in the trash it DOES NOT improve your bench

Its literally the opposite but ok

Hmmm- To use it correctly ; is in the Beholder... Cause isn't that why you produced it- to sell to Personal people...

The original ball is meant to be used in the same way?

If you want to gain more "balance" then sure. But you shaking there trying to steady yourself isn't going to build any more muscle then just DOING the exercise without this thing.

Garbage
