I'm pretty concerned with keeping my joints healthy. Lately I've been having a lot of cracking and noise from my knees when squatting, lunging, or just bending them in general. I do the fish oil thing and glucossamine (sp?), etc. Is this normal for the knees or a sign of potential problems? Is it sill safe to squat..I want to be able to walk right in 20 years and not in excruciating pain...
thanks for any input.
