I heard this "energy boost" point many times and never understood it.

I tried waking up at 5 AM for a morning workout for a year (with proper 8-9 hour sleep at night) and I would always feel tired for the remainder of the day, especially for a few hours right after the workout. Maybe this depends on the type of a workout. I was doing mostly powerlifting with heavyish postworkout meals.

I am now working out a few hours before my bedtime and it is perfect. I get tired and physically can't stay up late after an evening workout; it really helps with keeping my schedule stable (i.e. not staying up late in front of a screen).

Exactly the same thing I realized. Working out in the morning actually drained me of energy for the day and made me super sleepy instead. Running though, has the different effect and made me feel a whole lot more fresher and ready to tackle the day. So i guess it depends with each person what activity you do in the morning to get your body ready.

Same. My wife does it so she talked me into it when I switched jobs and had to start work at 8 am.

I was miserable. I finally decided just to do the gym on my lunch when possible. Much better.
