hey bro, good read so far, when I have more time I'll look at it more. It makes some sense, but I think the examples they used aren't as relevant to a seasoned trainer. Lumberjacks typically carry more bodyfat, gymnasts are typically much smaller than 200 lbs, as with rock climbers. I think what worked for Arnold, 99% of other people wouldnt do well with. As for modern day bodybuilders who do well with high volume, most are using 5x more steroids than the guys of that era and thats one of the biggest factors towards recovery.
The biggest problem I'm coming across with the HIT training is consistency. I think the first couple phases worked well, but my biggest gains were from the first phase where everything was a little more frequent and I was hitting the same exercises each time. My progress started falling off towards the end of the last phase where things were actually periodized much more. As far as the examples Darden used in his book, not too sure about those either. For one, he says that Casey Viator and Boyer Coe never touched steroids during their training with him and I call BULL****. And secondly, the main example he used in his book was a guy who couldnt have been more than 200 lbs and fairly decent development, but nothing even close to my level. So I cannot eat everything the program feeds me whole. I feel like I def gained something out of the routines, but at this point to say its a staple that works all year long, well I just cannot say that. Now, def not a knock on HIT, just a couple of the routines in his HIT. For myself, I feel like a mix between his style and Dorian Yates may be where the sweet spot is. Dorian trained HIT, but still did muscle splits and not full body. I like full body, but its getting to the point now where your hauling ass so much from one bodypart to the next, makes you wonder if going back to focusing on just 1 or 2 bodyparts the workout may get you a turbo boost in your development. And who knows, maybe going back and forth between the 2 styles of training is best. I like to take everything I learn and feed off it. But your article is very interesting, I will continue to read more and follow your log. Thank you
