Me personally... After I check in, I jog onto the mat, shake the referee's hand, grap the band and go to the edge of the mat. While putting on the band, I usually say a short prayer, not to win, but to keep everyone safe, on and off the mat. I have NEVER prayed to win. Personally I dont think it can help you win, but thats not why you should pray anyway. Not to offend anyone but my "prayer" doesnt even last 10 sec. I take a deep breath and go to the line, usually shake the ref's hand again. But praying is just a short time to relax and get your thoughts together, its not a stalling technique.
