Have you ever noticed what typically comes in a resistance tube kit? Only one of each band and a couple of flimsy handles. Blah.
Times are changing. Athletes have come to realize the potential and versatility that resistance bands have to offer, so why not make them unbreakable?
Resistance Band Superset features 3 matching pairs with snap-proof casing.  
The handles are knurled rubber, and we also included 2 door anchors instead of just 1. Let’s say you want to do chest fly’s: just clip your bands to 2 different door frames so that the resistance pulls from a wide angle. 

Each band is 50 inches from carabiner to carabiner.  The grey handles range from 15-30 lbs of tension, the red handles range from 40-55 lbs of tension and the black handles range from 60- 75 lbs of tension.  Stack them together in any combination to achieve desired resistance.
