what happens when I feel a popping in my shoulder when I work out?

Your shoulder joint is held in capsule that is not completely sealed, that is that it is sealed by muscle, ligaments and and an articular capsule made of cartilage, however it is not completely sealed which is good so that it can move more freely, but it can also make the shoulder easy to pop out of its socket.  That popping sound in your shoulder is probably the whole shoulder joint capsule making contact with another bone in the shoulder joint area, like I said it the joint is not completely smooth and when you work out a movement might possibly put enough stress on the joint capsule to come in contact with another bone in the area creating that "pop" until it returns to its normal position

Tendons don't "crack". Any popping is usually a bubble of nitrogen in the joints that is being expelled. It should not result in any damage.

You don't pop into a split, it takes time.  You have to practice stretching until you can do it.  No bouncing.

make sure when you breathe in, your stomach goes out and your shoulders stay put. if your shoulders raise, then you are breathing incorrectly and will run out of breath. if you still have problems, go through the music again and try to find more places where you can breathe without breaking up the music.

Joints/bones I pop:\n\nKnuckles\nWrists\nElbows\nNeck\nKnees\nAnkles\nToes\nSpine\nBreastbone\n\nYou can't technically pop shoulders, but sometimes I'll stretch until I feel the bone pull out of the rotator cuff a little, too.

That is usually the tendons that pop and ususlly means nothing. As long as you aren't putting the knees through a lot of repettitive motions which can, over time, cause problems with the knees. Yoga, pilates and those exercises are less stressful on the joints. Usually if there is no pain you don't need to worry. It's normal. If you start to feel pain, stop and see the Dr. Good luck.

Most likely, you are over doing it. You need to back off the weight amount and build up to it. If you are putting excess pressure on your diaphragm, such as with power lifts and jerks, it can cause nausea.

Sounds like you could have strain in your rhomboid muscles, which attached the medial wall of the scapula to the spine. There are a couple ways to help this. \n1. Exercise with light weights- dumbell rows\n2. Stretching\n3. Isometric exercises such as corner pushes- go to the corner of a room and put one hand on each wall, bend your elbows so your upper body moves towards the corner. Squeeze your shoulder blades together until you feel the back muscles engage and hold it for one minute. Do this 3 times in a row, 30 second break.\n\nI'll send you a link for some other exercises.

When your torso (chest, abdomen) receives significant force by a blow (fist, toso hitting the ground after a fall, etc), the reflex reaction is for the muscles of the torso to tense up.  This includes your abdominal muscles, muscles between your ribs (intercostals), neck, etc.  This forces the air out, and your diaphram can not overcome these muscles to inflate the lungs (when your diaphragm contracts, it causes the lungs to fill with air).  So for the second or two that you're torso muscles are in "spasm", you can't take in a breath.  They spasm as a reflex, that mother nature has built in to protect from another forceful blow that could damage your internal organs.

Are you talking about shoulder pain?  Yes.  If you injured yourself up there and are continuing to do your usual routine of pushups, you may be aggrevating the injury -- making it worse.  Hold off on the push ups for a while or at least cut down on their number.

You are either doing something incorrectly and straining your back or you are using muscles that are not used to being used, in that case you will eventually break them in.

My understanding is that it actually hurts it.  If poping it everyday for many years, arthritis could actually form and cause even more pain and make it harder for you to move.  If you are having problems with your back, go see a doctor and see what can be done.

It's hard to tell from your description, but it might be bursitis. Bursitis involves swelling of the bursa, which are little sacks that help muscles glide smoothly over bones without friction. When the bursa swell up, movement in that area can be painful.\n\nSee link below for more information.

Simple.  The shoulder tendon gets squeezed by the bones when you lift up your arm.  It hurts but gets better with time and rest.

If I'm understanding correctly, the area you are refering to is a set of muscle called the Trapezius. It covers most of the upper half of the back reaching upward to cover the central part of the back of the neck. The trapezius supports the weight of the shoulders and must contract strongly to rotate the shoulder blade every time you raise your arm(s).\n\nSince it's a recurring pain, you may have trigger points (knots) built up in the muscle. A good way to find them and massage them out yourself, is to get a tennis ball and place it inside a sock. Back up against a wall with the ball placed between your back and the wall. Having the ball inside a sock lets you hang on to the end and drape it over your shoulder for more control.\n\nHave the ball sit along side the bony ridge of your shoulder blade. About an inch to the side of the spine. Now gently and slowly move your body so the ball rolls up and down the whole length of your shoulder blade. If you hit any areas that are extremely painful, you have found some trigger points (knots).\n\nDo this 6 or more times a day if you can and apply heat afterwards.\n\nSince it sounds like you do alot of working out, you may benefit by getting The Trigger Point Therapy Workbook, by Clair Davies. It has saved me hundreds in therapy bills. Good luck.

I have no idea what joint you are referring to but you likely pinched a nerve. Don't push it as you will just make it worse.  The stiffening is the muscle tightening because the nerve is injured.  You shouldn't do anything until it's 100 percent better.  It's very easy to injure yourself when you are being athletic so don't forget to do warm ups etc.  All the things you do now will come back to haunt your body later...TRUST ME on that one.
