yes i just went through that. brachialus. it started about two weeks into me messing around w/ a planche progression during my down time. it lasted about six weeks. then it stopped. i researched a bit and gots many answers. asked a friend who's a pt even. blah blah blah rest. was the answer. i don''t think anyone really knows other than overuse.
What really feels weird is when you get a muscle twitch in your glutes. I think it is sometimes a result of heavy lifting and not necessarily from a mineral deficiency. I'm pretty well covered between ZMA, my multi-vitamin and my diet, but I still get twitches every once in a while.
