Is it okay/normal for the inside of my hip joint to pop when exercising?
Your joints are filled with a lubricating liquid called synovial fluid. (This is what Justin is referring to when he says something about lubricating your joints) There are bubbles in this fluid and often these bubbles will pop and make it a sound. It the same biophysics you hear when you crack your knuckles. As we get older, the fluid becomes thicker and less plentiful, so there tend to be more bubbles popping as you warm up the joint.
If it's just a sound, then you're fine. It means that you're hips are tight. Go slow and proceed at your comfort level. If you're joint it popping out of the socket, that's a a concern and you'd need to see your doctor. Since you said it didn't hurt, it seems like the first one. Is this helpful?
