What a great thought experiment! I’ll toss some out - the theme really being versatility.
Equipment: I’m going to second the smith machine. You can do absolutely anything on it. I was thinking power bar, because it is the ultimate in versatility, but in real life I’m going to get annoyed without a rack - the smith gives me some bang for the buck and now I’m also knocking out pullups and those types of things.
Just so I’m not a total copycat, I’ll toss out another thought: the cambered bar. Similar reasons as the really cool trap bar at the top, I’ve just never used that.
Food: it’s probably ground beef for me. I think it covers all the macro and micro nutrient bases, it covers me on creatine, and I just plain don’t get sick of eating it. Plus I can significantly change the texture/ style (much like eggs), so it creates different meals.
Book: It’s Encyclopedia of Modern Bodybuilding for me. I have actually found a lot I don’t like in there, but it’s such a combination of compendium, motivation, and practical application, it simply can’t be beat (except maybe by Dr. Stevenson’s version).
Again, to add something new, if you just want a blueprint of what to go do, John Meadows more recent programs (High Evolutionary would be my recommendation) give you a meal and supplement plan, sleep and recovery crash course, and repeatable program/ principles complete with video examples.
Conditioning: My cheater choice is the Rogue Yoke bar, because it gives me extra options for equipment. If I did this, my equipment is a power bar.
If I’m not cheating the game, and this is a vacuum, it’s the Prowler all day. There’s no planning involved and it makes me look cool.
Supplement: In a vacuum, it’s protein again for its versatility. My favorite specific supplement is Surge Workout Fuel. In context of my food being ground beef, that would probably be my choice here - I like periworkout carbohydrates.
Recovery: Sleeping? I don’t know. I like walking the dog and getting in the hot tub, so I guess I’ll choose dog walking.
Sport: Basketball, if only because I can still play and it forces a lot of athletic movement. Other sports were my “favorite,” but I just can’t do them anymore without them taking more than they give. Basketball is still fun, it doesn’t absolutely destroy me, I have some extraordinarily minor skill, and it forces all the things I don’t do in the gym.
That was fun! As I went through, my brain had to decide how to deal with each choice on its own vs. in context of the other choices - great idea.
