I have had my powerball for about a week now and i am wonderng roughly how long it should take for a noticable improvement in strengh assuming you do around 15 mins a day?

Just like to compliment the makers of this ingenious product, it is totally addictive!

Depends how intensive your 15-minutes per day is, but I would say that with heavy use you should notice a difference after about a week.

I recently spent a few weeks using my Powerball gently, but for about 2 hours per day, and noticed a marked improvement in my arm muscle definition after about a week.
