No shit? That's great. I guess it's not so miniscule as it seems, as far as your shoulders are concerned
BTW, I didn't work out until 9 pm last night and I didn't get done until 11 pm. That's right! Two hours. I had other stuff to do and it was a low rep "strength day" which meant a series of single and doubles with whatever rest I needed. Plus something similar for pullups. Plus some db stuff and shoulder prehab then post workout stretching. If I tried to keep every workout I ever did to an hour or less then I would be placing very ridiculous limitations on my options. The time should fit the goals of the workout first and foremost, not some overstated 'one size fits all' bullshit about cortisol.
LOL, I saw Phil Phister on TV recently. Works out in the gym twice a week basically beating himself to death for hours on end. I personally am not going to say, Phil, you'd be stronger and bigger if you kept it to 45 minutes
