Flexi-Sports Flexi-Bar Standard red I use the bar on a regular basis at home almost every day for about 10 minutes, in addition, I have made 20 workouts in a group with a physiotherapist. And I've tried both the original felxi bar staff and imitations. The original is the most expensive but also the best device I only can recommend !!!! For people with back problems weak connective tissue, it is the training device par excellence
