What is the variance in your weight Show vs offseason. I know some say not to gain to much but how do you know ??

yes, you definitely do not want to let yourself go when you are not prepping for a show. My figure trainer Damian Segovia probably put 10 pounds on me off season for my last show. It is good to add your calories in so you have energy to lift heavy weight. The idea is converting those extra calories to muscle, so be careful about storing too much fat or you will have a lot of work to do during show prep!
