I love my air climber. What an ingenious piece of equipment for the price. Last year I bought a [...] elliptical and wouldn't use it because it was so boring. Then, I had back surgery in May 2010 and was afraid to exercise again. I have always hated aerobic exercise and loved lifting weights. This crafty little machine takes care of aerobic and gives you the resistance. And no impact!!! Great for my back. You get a good sweat. [...] I got just what I was looking for. Yes, it is a bit loud,but who cares? Turn up the TV or the music and ignore it. I absolutely love this machine. What a great buy. I can't say enough good things about it.
