What happens to muscle fibres during rest-pause?

Post by tostig » Sat May 15, 2021 8:39 pm

The other day, I was trying to dumbbell press 10 reps to failure. But I could only reach 8 before I felt I couldn't do another one. Then after 30 seconds I decided to continue and pressed another 3 with the same weights when I called it quits before reaching failure.

So what happened during that 30seconds of rest that restored my strength or endurance? Did some muscle fibres repair themselves already?
