You can take this great exercise tool with you anywhere, it's used to strengthen the whole body, but it's best for shaping the hips, glutes and legs. There are three variations of resistance and each has its uses for both the beginner and advanced exerciser.
The heavy version is for the really experienced and therefore I use it only minimally so far. The material is very high quality and the design is beautiful. I only take a star off for the rubber strip being so wide, because it is hard to hold in the hand when practicing upper body.
