If you know you won’t make 4 rounds consider scaling to 5,5,5 and making it a 7:00 amrap sprint. I woke up to my alarm at 8 and had sore arms and hands. But back to the 4am hunger, I got up and ate some nuts and chicken bombers and had some milk then went back to bed. It felt like if I hit it as hard as I could against the wall I wouldn’t feel a thing, it would just bounce off like rubber. Yes, my arm felt like rubber from below the shoulder all the way down. Last night I woke up at 4am starving, awake, and with a rubber arm.
