I saw this challenge a couple of weeks ago and I've just come back to it. I've just taken the test. 50 reps have left my upper body shaking as I type this. - quite surprising for a 45 y.o. 10 st weakling with no upper body strength and sticks for arms. (No, I didn't rest on my knees, or the wall.)

I'll be starting week 3 col 3 sometime soon, but just let me recover form the shock of this first.

I see some improvements already in others who've already started. Well done. It gives encouragement.
