Cardio with Eliptical Traininer/knees

[Animal Cracker]

For all those who use the eliptical trainer on a regualr basis, I have been hitting the Eliptical trainer 5 times a week for 35 minutes. Lately my knees are killing me! I usually pop a Naproxen about 30 minutes before, and I am good to go afterward. Just curious if anyone else gets a bit sore in the knees after continuous use of this machine.

I never used an eliptical trainer, but from what I understand they're supposed to be very low impact (basically NO impact). If I were you, I would go to a sports med. doctor. You may have a problem with your knees. I won't go over the possible problems, but better be safe than sorry.

Seeing that nobody has answered this thread so far should give you an idea that this is not normal for a low impact excercise.

Good luck and get that looked at before something really goes wrong.
