Just a little bit of strengthening will effect a positive change. Quality is more important than quantity. Strengthening exercises only need to be performed two to three times a day initially, although the hand-on-head exercise (an exercise that activates the upper trapezius, elevates the shoulder blade, and helps teach you to use your shoulder blade when reaching up with your arm) can be performed throughout the day to relieve symptoms and retrain the trapezius muscle.
Once your pain diminishes and your habits are corrected, you may only need to perform the strengthening exercises once a day, once a week, once a month, or perhaps never again when your corrected movement habits are strengthening your muscles as needed, feeding your body rather than breaking it down.
