I was looking into weights and saw all the different resistance bands available on Walmart.com. I really like that these all fit into an included bag and can be stored easily into a drawer. So far I am glad I purchased resistance band instead of several hand weights (imagine trying to put all those in a drawer) I bought this particular set because it state they were "heavy duty". They seem well built and sturdy and the price was great! I would have spent so much more if I would have bought hand weights.
