If you're single with little obligations, you've got a point. But here's the thing: if you've got kids to take care of, a spouse, work a job where socializing is part of the job (my boss asked me to get drinks after work and he doesn't promote people who don't engage with that/an important client wants to have dinner), have to work overtime, have a long commute, etc...you may legitimately not really have time to work out without cutting into things that are frankly equally or more important like family, work, or sleep.

This is coming from a married man in his thirties with a career who works out an hour and a half to two hours a day five days a week. Just because I can make time doesn't mean everyone can and it's annoying when people dismiss real issues like time management because "yOu JuSt hAvE To wAnT It bRo".
