is there some reason why I couldnt do the medicine ball circuit or acceleration 1 or 2 with heavier ball than 6kg med.ball if I can reach the triple extencion?
We used a 7.5k ball (16 pounds leather ball) initially as that was the only one we had so I don’t see why you couldn’t.
Finally got a MY OWN med ball and I use it outside instead of in the gym! My neck has gotten bigger from using this ball… It’s a great tool and I find it fun to use this thing 2-3 times a week. Don’t see why charlie had a hard time getting athlete to use it?
