Nice write up! I made 1000 push-ups in 27 mins and 35 seconds this Wednesday. 2 days before I did 700. I started the challenge on the 27th of Jan with 300 push-ups.
My approach was to do 40 every 55 seconds 10 times, after 30 every 55 seconds. After 20 minutes I stopped caring about the time because I felt that I was there.
Good luck everybody!
