When I exercise or sometimes even just going up the stairs, my knees crack a bit. What's going on there? Is this something I should be worried about?

Anyone else have this?

Yep I have it nothing to worry about if it's not sore.

Thanks, I'm hoping it's nothing as I'm carrying on with my exercise regardless.

I had this when I was early twenties. GP said it was because my quads weren't strong enough in relation to other muscles. I did the exercises you are supposed to do to prepare for skiing and it went away.

OP, My knees do this too and have done for as long as I can remember. There's no way I could creep up the stairs behind someone the cracking is so loud . I once asked a physio at the gym about it and they gave me some technical jargon as to what causes it and basically said don't worry.
