The Air Climber is not just a stripped down step master. It is a workout in a bottle. It is very easy to use, portable, highly rigid, and it will leave a smile on your face after working out. The Amazing workout you get with it can be compared with nothing else. I have used treadmills and step masters of all types and never had the high quality workout that I've gotten with the air climber. I recommend anyone who is looking for a fun workout to use it.See More
