What was the routine on this for some of the more famous boxers ?
Did they do so many in a clip or spread them out over the course of the day whilst training ?

I remember reading while Ron Lyle was incarcerated he did a thousand push-ups in an hour.
I'm not sure tho if it was in a series or such as 100 at a clip or what,
I think I read it was one push-up every 3.6 second.
