Snatch grip dead's like push said are awesome indeed
I find they irritate the elbows do to the way the load is taken with the arms wide.
Having gone thru a year or two of some severe bicepital and elbow tendonitis issues
I would recommend a few things-
rest- stop the stuff that hurts
look at your programming
and see what may be causing it
for me it was a combination of repetitive things I do at work
and what I do for training
loaded pullups , snatches, and surprising things like OH squats where the culprit
take fish oil- if you do already take more.
allot more like in the 10,000 mg per day range
take a joint supplement- MSM chronditrin - cant spell that one. and MSM are all good
go for ultrasound treatment. It works.
