I bought these bands because the time has come for me to get into better shape! I am very pleased with them. My kids use traditional weights, but I don't like weights. With bands, you can accomplish many of the same goals. You can find dozens and dozens of exercises on the internet, including short videos. And unlike weights, the bands are portable, and come with a handy carrying case. The only reason I gave them 4 stars rather than five is I wish they were a bit longer. Aside from that, they are great.
