I found myself spending too much time in the gym and was looking into a home workout system -- something that's thrifty with floor space.  We looked into various systems and decided on resistance bands.  We choose Black Mountain because of the positive feedbacks, and they did not disappoint. Besides, Reistance Band has a natural synergy with our wrought-iron staircase!  I bought a pair of adjustable dogs' collars (cheap and flexible system!) and is able to loop them through the intricate iron works to the height and lateral space desired.  I noted the resistant poundage on the band itself with a label maker; bought myself a set of ankle straps (the one that came with the set only has one ankle strap and it does not have lining; I need two to do leg-raises), and I am set to go to work.  The quality of the bands is good.  The right weight can be arrived at by combining different bands.  Changing the bands with the handle is easy.  After exercising, put everything back into the bag provided for storage, and no one even know that I have a home 'gym'.  I still go to the gym, and I rave about the product to my friends.
