Input:
I've been using these bands for a little over two years now both personally and as part of my in-home personal training business. They are thoughtfully designed, durable and offer a wide range of resistances. The bag included is great for packing them up quickly and hitting the road. I've used other bands and the thing that stands out most with these is how easy it is to switch and/or stack your bands to get the resistance you want. The door anchor and ankle strap are great extras to be included in this bundle as well. I'm highly satisfied and have had many of my clients purchase their own set.
