After checking out the program I start on week three of the six week program. That's what the program at http://www.hundredpushups.com/ recommends.
This going to be an exciting endeavour for me. Can't wait to be able to do 100 puchups in one set.
On that site there is also a link to a program for two hundred situps and two hundred squats that I will be doing as well.
Tomorrow I will be doing the initial tests for those programs and I will let you know where I stand.
