I had the same problem, needing input. Never got it here.....Still....I decided to buy it....same as you are looking at. I am alone here, didn't need the top model. It IS a great supplement for sure.
I am up to 20-30 minutes. NOT easy, but I build up a sweat which is truly a teller at your workout!
