All systems go! Solved both issues.....I cut 2 little strips of an old yoga mat that I "cut" on for different things
and put one in each weight plate around bar with plate on (takes like 2 seconds) and put collar on. There you
go, much less, if any, twirling.....yay! I think because what I have,2 1/2 lbs, is alot less weight, they are gonna turn
more than a heavier weight. Also, I deflated my ball some, inflated it again, and pushed that plug in
very quickly and it went in. I think I read somewhere that you should wait like 24 hrs to put more air in a
stability ball when you first inflate it to give it time to stretch, etc...not sure that's why it worked this time
around. The old saying holds true, "Where there's a will....there's a way"! Now, I'm thinking about the
5 lb'ers....
Again, I love everything I got !
