What you are feeling is the Snap Reduction Technology cord getting tangled in the band and preventing you from stretching the band.
With your new bands you need to make sure that you activate the Snap Reduction Technology before the first use. It's essential but simple to do, just follow the directions below:
- Once you get the band set, take the bands out of the bag
- Take your door anchor and put it about waist height in your door and then attach an ankle strap through the loop of the door anchor. Basically making a chain link.
- Next, clip one end of the band on the ring of the ankle strap and then a handle on the other end of the band.
- Walk back slowly in a straight line and pull the band to the end of it's extension until you feel it stop (approx 16 feet). This unravels the snap reduction cord for the first time
Once you have done this quick step with all of your bands, your bands are ready to go!
After completing this with the bands just once they will function as normal.
