Query: The BEST! 30-something....

I'm 33, in good shape and was looking for a little variety to break up going to the gym everyday. I started trying Leslie's 1, 2, 3 and 4 mile work outs. These are quick, fun and challenging. It's shaken up my metabolism and I've managed to lose even more weight while doing them, coupled with a healthful diet of course. You will NOT be sorry! Althought 1,2,3,4 requires weights, you can use your own -- you don't have to buy the Walk Away weights. I had some 3 pound dumb bells which I used. Just choose 2 or 3 pound weights. You won't be alternating them, so just choose 2 or 3 pounds -- whatever works for you.Also - these are great tapes if you have knees problems. Even at my young age, I have a trick knee from a previous injury. I would love to do those high intensity FIRM work outs, however, I suspect the stress on my joints would be too much. You don't have to worry about that with any of Leslie's videos. Low impact, high calorie burning! You'll love it!!
