hip popping

[cmdubs]

When I was doing crunches on the decline board the other day I felt a popping coming from my hip area when I came up, then last night I noticed if I lifted my knee towards my chest when standing the same popping occurred. It doesn't hurt, just sounds funny.

Anybody heard of this before??

probably just a tendon sliding across your femur. my right leg does it if i raise it, then move the knee out.
