oh yeah, one last thing i'll share (you'll love this) - i have always had a decent set of abs (not necessarily too defined, but strong) - anyway, they have a tendency to cramp up on me and yesterday, i was doing some tricep push downs and something just above my rib cage "popped" out...it was about the size of a fist and pushed out right above my upper right rib cage. i had to keep my hands over my head and walk around in the corner while trying not to scream out in pain - suffice it to say i looked like a dork probably, but hell, the pain was something else - whether it was a hernia, i'm not sure, but i've got a date with the doctor to find out....
