Bests & Worsts Reviews from Amazon

I started using this 3 weeks ago. I have lost 1 1/2 inches off my waist. My core body and lower back feel much stronger. I've been dedicated. I'm using it 20 min in the mornng and 10- 15 min before bed. I'm 60 years old. I'm watching my weight and have lost 9 lbs. also. I use shoes. If you golf this is perfect motion to strengthen your lower back. If you really get going twisting, it's the same motion as a golf swing arms included. I can't recommend it enough. I will always do this. I'm going on vacation and putting it in my suitcase.
