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.
Somewhat recent social media trend of "how I start my day as a 19 year old millionaire tech-entrepreneur homeowner" (replace after 'as' with arbitrary garbage) where people pretend to social media that they wake up every day at 3 am to lift, run, meditate and prepare gourmet breakfasts in order to get an optimal start to the day. Most definitely a meme.
People in general thinking it is productive to to wake up early for no other reason than waking up early to be productive is also a meme.
You should have phrased your initial comment "personal trainer weekly first thing in the morning" and let people decide the exact hour it means for them. For me, for example, that would vary between 8am and 9am. Seeing the "6am" definitely triggers the "wake up in the middle of the night" meme.
