The resistance loop bands set that i had purchased is of excellent quality. I bought these to supplement my current workout when i cannot make it to my usual gym or standard workout, it really adds convenience to my busy routine. This allows me to get in a workout at home. You can use these also on legs as well as a well verse bunch of other workouts. What i like is you can also stack it to add more resistance.
Good easy workout on multiple body parts, can recommend.
