There is an airdyne bike at my gym and I've heard they are great for anaerobic and aerobic conditioning. However, there is no resistance on it and even when I peddle like a madman I don't feel like I'm getting much out of it (compared to how an elliptical wears me out)
Can someone give me an idea of the type(s) of workout you can do on it as I really want to put it to good use! thank you
