About the Challenge
I set myself this challenge in July of this year - it quickly became very addictive and quite a few other people got roped in!
The goal is to try and do 10 reps of pushups and/or 3 reps of pullups every day for the rest of the year - the catch is, you can't repeat any variety; it must be something different every day. I aimed for both and managed to keep going until mid October before running out of ideas and adapting the rules. I'm still dipping in and working on lots of different varieties.
It's not quite as hard as it first sounds; different hand positions, varying hand and foot height, plyometric variations - and of course, you can think up a whole string of progressions to work towards a particularly challenging variety.
I plan on keeping this challenge going indefinitely (with a loosening off of the 'every day' rule). I'll add a new video to the page every time I manage a new variety that I'm particularly pleased with.
