Fueling the machine…

We all have different diets and obviously different weight classes that we participate in… But every one of us needs to optimize our body for training and comp(if that’s your thing). Who goes with fasted training methodology vs some examples of pre/post training meals? I feel personally it’s something always being tweaked depending on current goals, but we all have some go tos or things we learned along the journey. I’m curious what the people have to say?
