Not sure why you were down voted, I remember a weight lifter who were at the top of their field in an interview saying he was so out of shape he couldn't play with his kids.

Weight training is great, in moderation, like anything else.

That's because he didn't train his endurance, not because strength training lowered his endurance.

You can train both and improve in both to a non-trivial level.

Endurance is a different adaptation that strength. Somebody who is merely strong will only be modestly more "in shape" than somebody who does zero exercise. Expecting strong people to be adapted for endurance is like expecting marathon runners to deadlift 400lbs.

Strong people can get in shape, though. Take a look at crossfit athletes.

Of course. For endurance I got into the habit of doing daily HIIT cardio. Instead of "Netflix and chill" it's Netflix and cardio for me. Pro tip to those who would like to get into the habit: pick a tv show and only watch it while you're on your stationary bike.
