You have a couple of options:
1 - Attempt to Peak for both shows
2 - Peak for the first show, roll into the 2nd show with whatever physique you happen to have
3 - Peak for the second show, do the first show with whatever physique you have “1 week out”
I think I like the 2nd option the best. That way you can focus on one show, but still get both shows in. Really, at one week out and one week later you basically have the same physique (except for the water/carb manipulation), so the differences aren’t going to be THAT dramatic in either direction.
The reason I like the 2nd option is because of the mental side of things… If you focus on the 2nd show and do shitty in the first show it has the potential to throw off your game plan. But if you do amazing the first show that might even motivate you to do better the second show.
I would say its best to focus on ONE. In which case it doesn’t really matter how you do in the 2nd show… So I probably wouldn’t pay the money to do it any way. I might do it as a challenge if I had several wins under my belt already, but other than that I think you are just setting yourself up to fail at one of the shows, which might throw off your mentality.
