You need to work on your abs and your lower back. Those muscles work together. If your abs are weak, you probably have a weak lower back as well.  That will make you slouch, make your stomach stick out more and cause lower-back pain and even constipation if your intestines are too crunched from your bad posture.  (My personal trainer taught me all this.)\nImagine this: your head is a block of wood.  So are your shoulders, your hips, your knees and your feet. Each block is attached to the next by a cord.  On top of your head is a balloon. Feel the balloon rise and pull all of the blocks into alignment. That's how you want to stand and sit.  Your shoulders should be slightly back.  If you are standing still, tilt your pelvis slightly forward and bend your knees just a bit. You'll feel your spine settle right into  your pelvic girdle. It's very comfortable. (That part's from my Chi Gong teacher.)

Get up and get moving around. It will help loosen up those stiff muscles.

have your knees and below as flexible as you can (so they act kinda like shock absorbers). keep your back straight, while in an almost close to a squatting position, but not that much.\n\nthis may sound hard at first, but believe me, this is the way to do it, and you'll look like a pro very quickly once you catch on to this.

My doctor told me to load up on calcium.  I also do sort of a yoga position.  It looks like that statue of Brittany Spears having her baby.  You're on your hands and knees with your arms forward.  It helps get into a comfortable position for a while.

Yes, wear a back brace like the people who lift heavy things wear. Those help for your back. Also, if the floors do not have a rubber mat, request one. They alleviate pressure on your feet. By comfortable shoes.

Get down on all fours and alternately thrust your legs straight back, kinda like a mule kick. Go for the burn!

Yes, see your doctor- he will do xrays to check out if you are getting this hump because of bone loss- (seriously, women are prone to this because of the calcium depletion).  He will give your exercises and he may right a script for a back brace- you will need to see an orthopedic surgeon for the brace.  Good luck and pull your shoulders back and sit up as straight as you can, when you can.

oh dear, you really need to either keep them firm from exercise or get a breast reduction or you will run into many back problems as an adult. Be sure to wear a full support bra. Also, please watch your posture, it may be more comfy with large ones but in the end you will be doing damage to your bone structure...(rounded shoulders , hunchback)

the best is Hyperextensions (Back Extensions) I do is almost everyday and already feel my back stronger and stronger....\n\nTips: Lie face down on a hyperextension bench, tucking your ankles securely under the footpads. Adjust the upper pad if possible so your upper thighs lie flat across the wide pad, leaving enough room for you to bend at the waist without any restriction. Start with your body in a straight line. Cross your arms in front of you or behind your head. You can also hold a weight for extra resistance. Slowly bend forward at the waist as far as you can while keeping your back FLAT. Do not round your back. Slowly raise your torso until your legs and upper body are in a straight line again. Do NOT arch your back past a straight line!

Tie your hands behind your back.

to get tight "body" the only exercise seems logical is a combination of sit up and push ups...try suiting yourself to the number of times you can do..if you can do 50,make it 50...if you can do 100, make it 100..don't cut down on your food...eat like a human..do not OVEREAT...try doing as many session as possible in a day..then you'll have a tight body
