it's like a treadmill. except the part you walk on is seperated into two smaller stepping parts w/ belts on them. and they go up and down almost like you are walking up stairs.. i know that it is something newer.
It's called the Treadclimber. Ooh, how I want one. It looks like so much fun. Check out www.treadclimber.com . It starts at about $1500, which is comparable to many "professional quality" treadmills.
wow. that is some money. haha our treadmill is about to die.. wont go faster than 2mph. i think it is time for an update. i might be stuck getting a $300.00 from sears for right now since hubby just started his new job. gotta save up the cash to get something like that. haha
