Did my first show and got 4th. My posing is off if I would have posed right I would have won the light heavy weight division. For you new guys doing your first show, you should practice posing 6 weeks out after your training session.
As for diuretics, use them wisely!!! I weighed in at 193 the night before the show, the next day a weigh ins, I was 186. I still had the biggest chest, back, and arms. My abs were the best also, my posing was off because I didn't practice enough.
Mike_XXL thank you for your help and everybody else too!
