this is the first time I have looked in this wing of the forum, despite being a long time C25k forum participant. I have to say I am quite shocked. C25k is such a brilliant, well-thought out programme with scince-based progressions and correspondingly high success rate. Whereas this 0-100 pushups in 6 weeks plan is an utter nonsense. The progressions are entirely arbitrary and unrealisitic and even worse there doesn't appear to be any advice anywhere on how to do the exercise properly, safely, with correct form... Most of the recognised callisthenics progression plans out there take 6-26 weeks to build through the elements before actually getting to a single full pushup with correct form. This just seems a recipe for disillusionemt at best and injury at worst.
I am really sorry to sound like such a party pooper, especially as I am usually the first to advocate strength and conditioning exercises but I am just gobsmacked by this. WTF are Laura and the NHS thinking?
