I bought the air climber and really like it a lot, but was wondering if anyone has had the problem of not be able stay on it long? After about 3 minutes I find my legs are tired, sore and have to stop. Does it get easier to where I can do the whole 30 minute workout with out stopping? Yes, I did stretch first.

It all depends on the individual. I have one and I will admit I really do not like it as much. I do work out every day and like everything if you feal the burn you are doing it right. Over time you will start to notice that you will be on it longer and longer. Your body is starting to work more areas of your legs. I hope I answered your question.
