> exercise-induced fatigue impairs complex cognitive tasks

Apparently your study is strictly about cardio.

Heavier compound lifts can surely knock me out for 30 minutes to 2 hours. I don't know how in the heck people train in the mornings. But a lot of this is because they are complex cognitive tasks.

Mornings (~6am), I often walk ~40min to my gym, do heavy compound lifts (~1hr total with ~2-3min rest between sets), walk ~40min back, and I tend to feel fine by the time I get back home. It's usually at the end of the day where the fatigue seems to catch up to me.

You’ve built up endurance already. The hard part of working out is getting to the point you got of not being completely sore for days after a single workout. I think that puts a lot of people off from consistent routines. I remember the first two weeks of track season no one could walk up stairs we were getting worked so hard, puking after ladder workouts 5 days a week. Eventually that petered out over the season but that initial hump from insufficient activity to being active is massive, and I don’t think a lot of us on the team would have surmounted it without essentially peer pressure and mutual support in suffering.

Oh, yea, for sure. One thing that keeps me consistent is that I know what happens when I take > 1 week off (which is sometimes unavoidable) and attempt to get back into it. DOMS⁰ for days.
