Overall, I really like these Athletic Works Mini-Loop exercise bands. I'm a tall guy, weigh about 180, and they are the right size. I think most people would benefit from using them. I put them around my knees while watching TV or reading, and exercise my thighs in comfort. I've tried all 3, and have chosen to start with the light tension, and slowly work toward the heavy tension. I also use them on my arms and even my feet. They are the right size for most people, although they may be small for very overweight people. I've tried other workout bands, but like these the best due to their compact size. They also are of high quality and should last a long time.
