This is one of the most versatile, effective training tools around. I can put an elite level athlete on my airdyne and have them in oxygen debt in very short order. I love incorporating short, high intensity bursts of speed on the airdyne into all kinds of workouts. It's a great total body warm-up tool, a great rehab tool, and a superb metabolic conditioner. Does not take up much room in your gym either, and mine is on wheels so it's a piece of cake to move it around, which I do all the time. I really want to get a second one.

The past week's workouts have included interval training on the airdyne. This bike is such a simple, great tool. I have had clients from age 11 to 81 training on it. It's very adaptable to any fitness level, I don't care how fit you are, or how deconditioned, this bike will allow you to train at the intensity that's right for you. I have also had people of all shapes and sizes on the bike. I had an 11 year old baseball player who weighs about 100 lbs, all the way up to clients whose weight I don't actually know because my scale does not go that high, but we are talking around 400 lbs. Both clients are able to get a meaningful workout on the bike, and honestly that is not something you can say about too many products! It would be impossible for me to put a 350 or 400 lb client on a concept 2, but they can get on the airdyne and push themselves into or near the red zone and get the metabolic conditioning that is so vital for them to get. Most people this size have knee pain and can't walk or climb stairs without discomfort, so that mode of movement is not an option.
No gym is really complete without one or two of these!
