Just found this, will be doing it in prep for my BMOQ for the Canadian Forces.

So, I challenge all you slightly outta shape or majorly outta shape people to join in and do the 6 weeks and do the 100 pushups at the end
I did the initial test and I am comfortable in the level 2 bracket (go to day one and look in the column for 6-10 pushups). I can do 25ish pushups as it stands, but I really don't want to strain myself too much, so I'm dropping it down a bracket just to make sure I look after my muscles and tendons and all that.
Started today and by god at the end of it, after pumping out the last few to failure I was totally wiped. Great feeling tho
