[QUOTE=jdhowland;861099]cjurakpt suggests some good sources. If you wish to try something outside of the trademark licensed schools here are a couple of suggestions.
Learning to relax a certain part of the body might be easier if you tense something else. I suggest upper trap/neck stretches to remind you how much distance there can be between the shoulders and head. Then try to utilize the scapular stabilizer muscles in your back to keep the shoulder blades from floating up when you punch. Some schools advocate punching with a “long neck and short trunk.” In other words tightened abs are balanced by tightening the back a bit, giving the sensation of a depressed or compacted ribcage. With the shoulder blades stabilized and “attached” to the mid-back the punch is delivered first with body rotation and trunk power. Then the arm is extended with whatever kind of exertion the style demands. (I know some instructors advocate arm extension first, followed by body rotation–if this is your style you still might try this as an alternative training method.)
Many people have trouble getting in touch with these mid-back muscles and can’t feel what they need to do to isolate them. Try depressing your shoulders while remaining relaxed otherwise.
Another technique is to punch slowly while imagining that the shoulders and elbows are very heavy; solid gold, if you like.
Good luck.[/QUOTE]
just to clarify, jd is describing mid and lower trapezius when he’s talking about scapular stabilizers / mid-back muscles; typically they are reltively inhibited, in contrast to the relatively more facilitated antagonists such as upper traps, pecs, subscapularis (a biggie) and lats;
the method he describes can work just fine - if you can’t “access” those LT’s on your own, there are a bunch of ways off the top of my head that I can get someone to, but most involve tactile feedback, either as resistance to LT’s to activate them isometrically, or re-positioning the costal cage, or de-facilitating upper respiratory inhalation (scalenes, SCM and UT’s) and promoting more decent of respiratory diaphragm during inhalation (usually by emphasizing exhalation first)
actually, this video is pretty good at explaining the motion LT’s do, although I wouldn’t necessarily start with those particular exercises and i would talk about how to coordinate a chin tuck and the breathing (usually inhalation during the first part at least) with it as well: http://mentalhelp.healthology.com//hybrid/hybrid-autodetect.aspx?focus_handle=workplace-health&content_id=3104&brand_name=mentalhelp
this is also a pretty good article on typical agonist / antagonist relationships that tend to promote a facilitated / inhibited imbalanced force couples (pretty much summarizing the work of Janda, Levitt and Sahrmann)

learning how to access LT’s will go a LONG way towards improving vertical orientation and reducing fatigue, as well as a nice way to “squeeze out” the mid thoracic zone, where you get a lot of stress-related activity via the sympathetic trunk / chain of the sympathetic nervous system running along the side of the vertebrae; overall a very worthwhile endeavor…
BTW, the reason this area gives u so much trouble is, I believe, a direct result of our bipedal orientation: if you are a quadriped, you are constantly working the agonist / antagonists in a on/off cycle, keeping them balanced via the wieghtbearing on the hands; so doing things in quadriped or on hands alone makes sense
