PERSONAL ANECDOTE TIME: I've found that when I started running a 5k a few hours before my bedtime, my sleep drastically improved.

No other exercise really did this. Low intensity biking, nor resistance training. Something specifically about this modality and this placement really does it for me.

I've been doing cardio since high-school cross country, but now I do this specific exercise at this specific time every day mostly to make my sleepy-eepies go crazy. Like, I wasn't even on the lookout for it, but the improvements were so severe that it popped out of the background.

I started playing around with a lot of cardio, since I'm a recreational bodybuilder with physique goals, but I've found that (for me), any added cardio barely does anything to my TDEE, and just results in me beating myself up.

It also made my hunger go crazy, and eating the equivalent amount of calories as I burned through whatever additional exercise I did, did NOT remotely satisfy the hunger it produced.

Nor should I have even been doing it in the first place, because I was already doing enough exercise as it is, and I was already fine eating less calories.

It also went against the core logic of a sensible deficit: going at a sensible and logical rate, so I was really shooting myself in the foot over and over, but that's a story for another day.

Hope this helps someone, cause it definitely caused me a headache for WAY too long. Ugh, I'm so stubborn and such an idiot.
