Heh, there&#x27;s a lot to cover. First of all, just go to physical therapy if you have any pain. Even if you know the rehab exercises, doing them with perfect form will be very challenging.<p>* Muscles typically work in agonist&#x2F;antagonist pairs. You bend your arm at the elbow, the bicep contracts, and the triceps lengthen. Straighten your arm and your triceps contract while your bicep lengthens.<p>* When 1 muscle in a pair is overly active, it will shorten and become tight while its antagonist muscle lengthens and becomes weak. This is imbalance. The weaker, lengthened muscle will often develop painful trigger points in protest. This is referred pain.<p>* To restore balance, you need to strengthen and learn to activate the lengthened muscle while relaxing (inhibiting) the tight muscle.<p>* Foam roll and stretch the tight muscles, strengthen the weak muscles<p>--<p>Upper crossed syndrome is common issue amongst desk workers. See <a href="http:&#x2F;&#x2F;www.muscleimbalancesyndromes.com&#x2F;janda-syndromes&#x2F;upper-crossed-syndrome&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.muscleimbalancesyndromes.com&#x2F;janda-syndromes&#x2F;uppe...</a><p>For this you would<p>* Need to develop: scapular stability, scapular retraction, and scapular depression<p>* Need to inhibit: scapular elevation<p>* Maintain neutral chin tuck in pretty much all movements.<p>* ITYW exercises: when doing Ts, focus on squeezing at your mid traps (mid back), with neutral scapular elevation. During Ws, focus on scapular retraction and depression at the same time.<p>* Wall slides or wall angels<p>* Band pull-aparts<p>* Deadlifts<p>* Farmer carries<p>* External shoulder rotations<p>* Face pulls, finishing with external rotation at shoulder<p>* Rows<p>* Reverse flyes (palms down for posterior delts, thumbs pointing up for more mid trapezius and other back muscles)<p>Before doing a heavy lift (like rows), you might do an activation exercise beforehand (Ts and Ws) to focus on activating the muscles you want to work (mid and lower trapezius).<p>Similarly, if you want to workout your (tight) chest, you ought to do activation work for you back (ITYWs, wall angels) to ensure that your agonist&#x2F;antagonist pairs &quot;remember&quot; each other and your chest doesn&#x27;t tighten back up too much.<p>Hopefully that should give you plenty of material to google with. I&#x27;d love to go into further detail (there&#x27;s plenty more to cover) but I mustn&#x27;t spend too much time writing comments on HN :)
