I didn't read Daddywaddy's post about one hour push-up sessions and I may be wrong . But isn't the whole idea of a one hour session is to do the max amount of bodyweight push-ups only? I've seen half hour sessions doing bwt squats, push-up, sit-ups, etc by cage fighter's and some others. No extra weight applied. Any hour session must be a real man killer with just bwt alone. Going to require a lot of recovery time at first. Let us know the results. Good Luck.
