Knee popping sounds while working out

It really can be several different things and may be worth keeping and eye on. If you hear a pop and have no pain it could be soft tissue bands that are harmlessly rubbing in the joint but if you are hearing popping and cracking and are experiencing some pain or alot of pain then you could be looking at cartilage damage or possibly a torn meniscus or loose bodies of the two floating around in the knee joint... I have No meniscus left in either knee, and no cartilage left in either knee and have been bone on bone for the past decade so whenever I am walking or bending my knee's are popping and cracking and making a host of noises... lol I would recommend if it keeps up and you are still having pain you might consider seeing your doctor and possibly getting a referral to an Orthopedic surgeon for a consult... Strengthening the muscles in and around the knee joint is the best way to reduce damage to the knee joint itself but you need to build those muscle up slowly if you have under lying issue and there again I good reason to seek medical advice.... Best of Luck

I get popping in my wrists when trying push ups and I cant do side leg raises due to popping in my hips (that's a bit sore)... slightly concerned

A lot of times popping is nothing, sometimes it's something. The only person who can tell you is a good doctor or physical therapist.

But, in regards to bracing. I have a couple if joints that are permanently braced, and a couple more that are sometimes braced. The wrong type of brace can do a lot of damage, and one of the big reasons permanent bracing is controversial is that it weakes your joints. Outside if medical necessity, putting on a brace so you are able to complete an exercise means you still aren't completing the exercise correctly.

Think about this for a second. It isn't just your knees. If your knees are wobbling, then so are your ankles and hips. A knee brace changes the mechanics of your knee and restricts motion, which puts different stress in your ankle and hips and back, etc.

No one here can recommend a good brace for you, because braces aren't universal. The type that works for be person won't work for another. Even good orthopedic doctors can be iffy on which braces are best. They've usually written a category, and then we've worked with bracing people and physical therapists to find the best braces for me.

If you are set on bracing your knee, I would strongly recommend doing so through an orthopedist's office. Braces are a band aid. They're compensating for weakness, and are covering up the real problem. Sometimes, that is completely necessary. But bracing one joint to get through a workout where you admit you have sloppy form without consulting a physical therapist or an orthopedist is asking for an injury. Maybe not to your knee, but to one of the joints that is connected to it.
