There's more and more research that says you do need to do some sort of resistance/strength training to minimize morbidity and mortality. It doesn't have to be weight lifting, but if you're only doing cardio you're missing something.

I don't minmax life for the same reason I don't minmax games. We had healthy people before the recent weight lifting craze; my strength training is rock climbing.

Most people did manual labor. Even if they didn't, everyone walked more, or rode horses, chopped wood, drew water from wells, and did a hundred other things that required using their muscles in a way that's just not necessary today.

That's weight lifting too. Bodyweight is still weight.

The weight training craze is far, far more recent than our shift to a sedentary lifestyle.

To have a higher quality of life in old age, you need to build strength in your youth. The shift to sedentary lifestyles has happened in the last 50 to 70 years, and that also coincided with an increase in life expectancy.

The comment you responded to about not "min maxing" https://news.ycombinator.com/item?id=46499625 only advocated resistance and strength training, not "weight training" specifically. It's hard to dispute that having a stronger body is better for living a healthy life.

None of that will bulk you like weight lifting nor is similar to weight lifting. Those guys were smaller. By our standards, they would do a lot of low resistance repetition, basically.

I mean, you are stretching the definition of weight lifting to unrecognizable. Climbing is not weight lifting anymore then walking is running.

Even weight lifting won't bulk you unless you actively try to bulk. Seriously, appearing muscular or bulky when you're fully dressed is actually quite hard to accomplish for most people (practically all females and maybe half the males). It takes years and years of gym work and diet that most people won't ever put in.

Rock climbing is probably going to be just as good at weight lifting. My understanding of the mental model here is:

Up until around age 60, your body adjusts your muscle mass based on usage. Somewhere around 60, you start losing muscle mass. If you have just enough muscle for day to day activities in a sedentary life at that point, then over time daily tasks like carrying groceries or standing up out of a chair are going to become prohibitively difficult. You need to do something that encourages your body to grow more muscle than you need for day to day life so that you can afford to lose some of it.

You are missing even more when you do just weight lifting. The weight lifting part is the less important part. Being bulky is easthetic preference, lifting is pleasant hobby for quite a lot of people (actually including me), but it is nothing necessary for health.
