I don't know what to believe anymore!
First I read that ellipticals are better than treadmills because they're low impact and you're kind of getting a fully body work out from them. Treadmills are not so good for the knees, and burning calories on an elliptical is generally easier.
NOW I'm reading nearly the opposite!
I'm reading that ellipticals are absolutely horrible for your body because your body is out of alignment. I'm reading that you're not supposed to hold onto the rails. I'm reading that using the treadmill properly will strengthen your knees.
I know when I, personally, use the elliptical, I get a much better, longer, and more intense work out than when I'm on the treadmill. It doesn't take much for my knees and shins to start giving me pain on the treadmill, which effects my confidence, which effects my performance. On the elliptical, I can ramp up the resistance and sweat up a storm, and keep my heart rate elevated for my full work out.
But now I'm terrified of injuring myself on one machine or the other.
Please, help!
