My wife asked for these to go with her exercise DVD but I think I have used them more than her. They are so easy to use and change resistance levels for a complete workout. I have a very good multi-gym in my garage but can achieve very close to the same results in less time using this equipment. The clips on the end of each band are strong but easy to use and also have a swivel so when you attach more than one band they sort themselves out and don't twist into an unusable mess. The handles have durable foam sleeves so are very comfortable to use. I put all five bands on for some exercises and they still don't dig in. The attachment for the door is simple but very effective, allowing even more exersises to be perfomed. In fact there is not a muscle group, if use use some imagination, that you can not achieve a decent workout with for these. Brilliant for everyone, from the beginner to the exercise junky. Easy to use and great results.
