I'm doing some upper body rebuilding after an injury and thought I'd try the Black Mountain Bands. I find them a great alternative to free weights and something I can pack easily when traveling. The door anchor that is included can be used both in a door stop or you can slip a dowel through the loop to stand on or to use under a door for a different pulling angle. I have two bands now and intend to purchase more as my resistance needs grow. Also, you can actually double up the bands as the pull handles are padded enough to hold two in your hands (I wear medium sized gloves, so smaller hands might have trouble with this). Also Black Mountain makes a set with removable/swappable handles to make multiple-banding easier.
