The 100 push up challenge

[southernsoftie]

Managed to do 22 pushups last night and that was after doing the session earlier so good signs so far!

I think Al asked the question earlier, but it's not clear from the site if you do any more 'exhaustion tests' between the initial test and the final 100, yet you all seem to be updating your max quite regularly. Have I missed something? How often should we be doing them?
