1st of all, sorry it has taken me so long to respond. I hadn't checked this forum in a while.
What have I tried... My background is mostly in permutations of Westside, but it's becoming gradually more Sheiko-ish (but not exactly as I'm sure you can see in my log). My gains really started taking off when I started doing RTS, which is why I'm such a big believer in it.
I haven't tried a traditional sheiko template. I've thought about it, but I have never been able to let go of the things I know work for me to start the tinkering process all over again. I prefer to let my training evolve over time. Evolution, not revolution.
I have tracked my diet and a host of other factors before, but I am not currently doing so (mostly because I am too busy with a new job, moving, preparing for a meet, and trying to write a book). I have counted protein/carbs/fats in the past, but I can't say I'm an expert on that stuff.
