Welcome to the Army, perhaps. Ask them if they're ex-mil, or are copying someone who's ex-mil.
25 years later the concept of exercising on anything but an empty stomach feels weird to me. Like if you put forth a true 100% effort how do you not puke?
Practice. If you've never done it before, it takes a few days/weeks to get used to. Also willpower.
I'm absolutely fine with it and prefer it, like many other people. It's definitely not "torture".
Maybe it isn't for some but mostly it's about overcoming the change in routine and there's no shortcut to changing or building habits, it's just willpower.
Like calling something torture - that you voluntarily do to yourself because of an expected net positive outcome.
For the respect of people who suffers or have suffered from torture I think we should avoid that kind of hyperbole.
Same goes for calling sexism on any joke about gender differences. It's kind of disrespectful to everyone who has suffered from the real thing.
It's just habit. I stopped eating breakfast in primary school and always preferred doing sports in the morning. Currently doing fasted weightlifting/cardio 5x a week first thing in the morning.
I'm currently doing only one big meal a day for lunch so technically that's fasting since 2pm the previous day.
then there are the 'early birds' who get up at 5 am and have a 4 egg omelet before the meet. they disgust me :)
A few friends of mine fast intermittently and train in the morning before eating but it's beyond me how that is not just pure torture.
