As you noted, I didn’t have a real point about the rotator cuff and HIT, per se. Really, it was more of a cautionary tale of how easy it is to get injured, in the pursuit of becoming more “fit.”
ErinElizabeth said it best:
“…for the long haul I think whatever exercise you actually enjoy doing is the best bet.”
If you want to work the rotator cuff muscles specifically, I’m sure Google will turn-up some suggestions. Or, you could call a local Physical Therapist (P.T.) and ask for some advice. You might also post on the web sites of Robb Wolf, Mark Sisson, Keith Norris, or Doug McGuff.
Speaking of McGuff, check-out his video I posted here:
NOTE: If you watch the entire video, please be aware that the conference is called the “21 Convention” and is geared toward the 20-something males. Accordingly, the language and inferences can be a bit loose. I probably don’t need to say much more. :-)
