Someone asked me: How HARD can you FLEX your MUSCLES? Do you think you can PUMP them up and GROW them just by FLEXING REALLY HARD? I think he will find the answer after watching this video... I didn't think my BICEPS could get that far! I didn't think SQUEEZING that HARD would POP OUT my 6 PACK ABS! I really didn't think I could generate so much MUSCLE PRESSURE to give myself an ORGASM!
