This may be a little random and all over the place........
As far as gym lift training, the 'magic routine' is a myth, not that I can't stand to learn a thing or two, but to me it is a no brainer, train progressively and eat for your desired bodyweight goals, I'd really just bring up routines out of curiosity and because I am a dork who likes to discuss that sort of thing......I'd have more specific questions with PL gear and Strongman implements, more so because I don't have huge amounts of experience with either.....I think top-level PLs could be a WORLD of help in giving tips on how to work the equipment.
I'd definitely ask the PLs their thoughts on equipment and if they feel it is out of control and how they react to both sides of the argument. I'd ask the Strongmen what lifts they feel give the most carryover to their events (I would ask out of curiosity and take it with a grain of salt as it is individual and if you asked the top 10 strongmen this question, you'd get 10 different answers).
With diet, again, you'll get a million different answers from pounds and pounds of lean meats a day to Twinkies, Taco Bell, and Guinness.......I'd actually be more interested in what weight class guys do to be honest with diet.
Not that I am a top level anything.....but to share some info. I have acquired over the years regarding strength athletes......weight class guys like to come in at the top end of the class while carrying as much LEAN muscle as they can......heavyweights like to weigh whatever they feel allows their best performance.
If I can debunk another myth, I will....it is the "exotic, designer drug" myth....strength athletes love what has worked for decades, test, dbol (or anadrol), deca, equipoise.
Illuminati said what I have come to find with dosages (with heavyweights) .....strength athletes I have discussed this with like a year-round 'maintainence' dose of 500mg test/week and they typically switch esters around every couple of months....as a competition draws near, they up the dose typically to anywhere from 1,000-2,000 mgs/week and add in the other goodies, some like deca, equipoise, orals (if they can tolerate them). As a side note, I agree that guys seem to like about 10-12 dbol tabs a day.......personally, that shit always made me sick at anything higher than 15mg and I personally feel any more is TOTALLY overkill, but thats just me, I never did well with orals and sides.
Lets see.....most athletes favorite stack is test/deca/equipoise on average I would say.
As far as Bodybuilders go, I can't answer because I don't care in the least, I do know lots of ball licking is involved though, lol.....
And drugs with the weight class guys, I never really asked because I don't care either.
