Hi Debbie,
I'm a big fan of Leslie's programs. I got a great one from QVC item number F25528. It's called the walk off the weight at home fitness program with weighted gloves. So far I can't make it through the four mile tape. It's 65 minutes long and very challenging. This is one you might want to check out. I'm not sure what you want to spend but QVC had the best price that I saw for this. And no I do not work for QVC but I do like to pass values along. If you want to check it out go to
www.qvc.com and enter the item number in the search block and it will pull it up. Good luck and great walking.
Oh and if you are interested we have a thread on here for Air Walker/gliders and regular walkers #23 and we'd love to have you join us.
