muscle cramps when flexing??
ok .. I get cramps/spasm whenever I flex Hard
example: when I flex my bi's, arm is at a 120 degree angle and I give it a good hard flex, I won't be able to hold it more than 3 secs before it starts cramping up.. and If I hold it flexing, for a bit longer with standing the pain and when I release my flex but still have my arm arc'd at 120 my bi's will stay pumped/hard for a bit (sometimes it'll pulsate/jitter a bit) before going back to normal tension.
basically I can cramp up all my muscles tri's pec's etc,.
it's kinda neat but is it normal??.. all of my buddy's think i'm weird hahah
