I found this link and thought this would be interesting to try.
I've always been horrible at push-ups... not sure what it is exactly, just bad core strength I guess.
I'll do the initial test either tomorrow or on the weekend, then follow the rather simple program until I can do 100 consecutive push-ups.
UPDATE - I did the "initial test", 13 push-ups. Not great, but better than I expected.
100, here I come! :)
