For sure, there is some kind of optimal balance to target. I've pushed myself so hard at times that I disrupted my sleep. For example, I bought a used Kickr and decided to do a FTP test at 9pm. This was not the smartest idea.

Running has been the goto for me. Can push myself on a 5k run in the evening (6pm) and when 10pm hits, I'm 2x more tired than normal.
