If you’re on gear, you can do that if you feed your body enough.
For a fight
I train 2-3 hours ed 5-6x ew for 4-6 months. Mix of high intensity conditioning, skills training, sparring, and weight lifting.
And last 2-3 weeks I go to fight camp 5-6 hours a day. For maybe 6 times a week all out. 2 hours group in the morning, 2 hours group in the afternoon. And 1 hour one on one with my trainer. And I try to still lift light after the day.
This is common for most fighters. And you wonder why pro athletes are on gear. It isn’t that it gets you big and strong. It’s so you can actually recover and train more.
I seriously dislike none athletes saying athletes are cheating. They wouldn’t last 1 day at fight camp. I can understand why a natty athlete would say someone on something is. Because it isn’t fair when you put two guys on the same training schedule.
