Start small and don’t dive into the deep end. Do that and you might find sticking to it easier. When you’re a complete beginner the bare minimum amount of work is enough to start seeing results in a few weeks/months.
Only go hardcore blood and guts later on if that’s something you really want. Willpower/motivation is a finite resource, so making exercise absolutely miserable from the very beginning is a good way to fail after a week or two tops.
I think part of the point isn’t so much to dunk on these dudes specifically (although they’re not great people for choosing to actually go so I don’t feel bad for them) but rather to point out that not even a week ago Hegseth was yapping about the “ideal soldier” to a room full of men who are way more knowledgeable and qualified than he is. Meanwhile the only folks that seem to wanna actually do this shit in Chicago are less than ideal specimens by Hegseth own fucked standards.
