and a bad exercise for someone over 50 and has a bad back I was able to get about a minute-and-a-half before I collapsed. I do plan to keep it up and hopefully get to 2 minutes and over
Taking into consideration that i have back problems " I have started doing the 7minutes workout for about a week now. I gotta admit I'm feeling the burn ! I had been doing Chalene Johnson workout and I didn't get the results I'm getting now !
