The Air Climber Deluxe isn't terrible but it's a tad on the loud side. It got my heart rate up, made me sweat, and wow could I feel it in my legs! The more I used it the more definition I got but it mainly came in my calves and not as much in my thighs as I would have liked. All in all going up and down stairs would do the same but with this I can watch t.v. at the same time. It sounds lazy but if I watched tv I actually excersised longer.
