Hey there! Another cop in the fold! I'm glad I'm no longer solo. In regards to shaping up for PP, I workout four days a week so there's no problem there. I do buy gel inserts for my shoes to help with the standing process.
The only request I have is to wear antiperspirant/deodorant, perfume, cologne or any other item that can take the smell away. It gets pretty bad once the third set comes around.
Also in regards to shampoo, please have pleasant smelling shampoo. When you headbang, the scent travels like a mosquito truck. I remember during the Firewind set a few years back, there was a guy in front of me who headbanged continuously and had some GOD AWFUL medicated shampoo he was apparently using and it was absolutely horrible. I tried to scoot a little left or right, but it wasn't happening. I had to withstand the smell because there was no way in hell I was sitting.
Don't even get me started on those who fart in the crowd....
