Sports medicine: i am not able to find weight training exercises that will result in better posture. focus: keep shoulders back. give an online link?

Not wt training: Try palites or ti chi or yoga or feldenfris these forms of movement and posture/breathing exercise may help.

Agree with links: Agree with links that were already shared. Along with those exercises, i also like rows, lying with a foam roller the long way along the back, chin tucks, (witch hazel) sitting on an exercise ball or ball chair can help posture, and moving the computer monitor up to eye level to train posture (proper ergonomics).

Many exercises: Of course you should review with your physician prior to starting any physical exercise regimen for safety purposes. But the types of exercises that improve posture focus on strengthening your core(as in your back and abs) and balancing the anterior(front) and the posterior muscle of the chest/upper back: look at http://www.prevention.com/fitness/strength-training/exercises-improve-bad-posture
