Just stick on those takkies and take a walk! It's cheaper than an eliptical trainer anyway! I've got that walker/step thing that I now use and it's great... going to woolworths this weekend to buy something that I saw on telly, they aren't too expensive, so if I have enough money, I'll get you one too! It works on the resistance of your own body and is just a strap that straps over your feet..!
