    Awesome Bands and Great Workout. Very surprised.

    So far terrific. The bands are high quality and the video workout is very challenging. I did get the XL gloves and they help the hands. They run small for a XL. I had to stretch them out. And the gloves would be great if you could operate the iPhone or iPad without taking off the gloves. I think that can be done. Using the gloves and iPhone go hand in hand. Taking them off to press play gets yo be a challenge.
