Although I have used resistance bands with the Physical Therapist and also with my Bowflex, this is the the first set of Bands that I have purchased.  I really enjoy these resistance bands, they are a safe way to perform practical, strength building exercises and they can be taken anywhere.  The resistance bands have helped me recover from Knee Surgery and also from Tendonitis. This is a great set for a great price and I recommend it to people of all body types!
