Well read on high volume, cortisol and testosterone. There is not absolute relationship between libido and test but a strong correlation
I might not be right but that is what I experienced as I get older. High volume = low libido. If you have a better explanation than low test, go ahead
I spent most of my teenage years in the late 80s early 90s doing bb style workout. Biggest regret of my training life. Apart from looking better and bigger it didn't really help in anything else. I would have been better off power cleaning to increase my speed and vertical. But I didn t know better. Thats what my sons are doing and it shows on the field and on their body.
My 14year old has exactly my body type and structure. So I can compare. Both natty, he train smart, I was training bb style. I look at pic and we look mostly the same, but his improvements in performance compare to mine are off the chart.
My point, if your natural, train hard in a well balanced way, perhaps adding a bit off bb style training here and there on lagging muscle, you will end up looking more or less the same, but your performance will greatly differ
