[Reincarnate]

fantastic video tutorial (IMO) on squat grip by Mark Rippetoe:

Summary:

-Thumbs above the bar
-Narrow grip
-Elbows up at all times, don't let them drop or it'll loosen the upper back
-Keep the wrists aligned with your forearm/back of the hand, nice and straight
-Keep the weight off the arms/elbows -- on the back only

Basically tendonitis is a real common result of the squat because a lot of people apparently hold the bar incorrectly. When you hold onto the bar (esp with thumbs under), you risk flexing your wrists which means much of the load is distributed down the wrist/into the elbow, which is exactly what you don't want.

I can finally walk again so today at the gym I am going to, well, squat again and probably render myself immobile for another week. XD XD XD
