I'm making my Xmas list for my hubby(he's usually in the mall Christmas Eve )Anyway, on the top of the list is the new series(he already ordered them). I noticed you need a exercise band for some of them and I don't have one. Can anyone recommend a brand and one that comes with different resistance levels? My DH wants to do some of the DVDs with me and he'll need one too. BTW we have Sports Authority and Dick's Sporting Goods near us. And of course the internet. Thanks for your help!
