To add to that, people tend to forget that rest is just as important as the exercise itself, otherwise you don't fully recover, muscles don't grow etc.

If you're meeting your personal trainer at 6am that means you need to be falling asleep by 9pm or something otherwise you're sabotaging yourself.

Meme? Exercising first thing in the morning reduces to zero the probability of skipping, you do it, you're done, nothing can go wrong in your day that gives you an excuse to skip. The personal trainer is the motivation pill you need to establish a routine, and forced weekly reset point when you inevitably fall off track now and then. From this anchor we can slowly grow into a healthy routine of exercising 4x per week that we need to stay mobile and healthy as we age. If you want to live a long healthy life, eliminating the possibility of not exercising over long time horizons is literally the #1 most important thing you must do.

Sounds like you’re projecting a bit. Lots of reasons one might be up at 6, other than hype or a “meme”. For me, it’s the only time I have to work out (with a job and smaller kids).
