Maybe. I suspect it has more to do with baseline activity level and type of workout, but I could be wrong. I only have 1 body. IME, If I do nothing all day, I'll feel sluggish all day. If I take a 30 minute walk or do some squats, pullups or overhead presses, it will get my heart rate up and I'll feel more awake afterwards. I generally don't push myself to the point of exhaustion with exercise.

I will defer to your many decades of life experience.

I just noticed that in my 53 year existence, only by the past 10 years, a morning workout (which I didn't do prior to that) was figuratively and literally eye-opening, not just physically but mentally.

Specifically, it was the Orangetheory workout.

And I regretted not discovering it sooner, and mainly I blame people who didn't emphasize not just the physical but the mental boost
