3h every day sounds like you either have incredible genetics, your workouts are low effort or you're "chemically assisted".
Now that I'm older, if I have my workouts (lift, cardio, and jiu-jitsu) all line up on the same day like what happened this week, it usually means a day or 2 of easy cardio and yoga after.
I used to run a half-marathon every day for ~two years but eventually got injured. Weights was the best decision to switch gears.
