Dude! That is so true. I inadvertently found this out years ago. And certain posterior chain exercises, like the hip abductor machine, and a few others, yes you can literally do almost everyday without burning yourself out. Heavy squats obviously would not be wise to do everyday or close to that, as that would be overkill. you feel the positive hormonal affects immediately afterwards, and as youre walking out of the gym. And you would develop your posterior chain, and start getting more attention from women.
