I've recently started the 100 push ups a day challenge. Currently I am on day 5 and I started having difficulties completing one hundred push ups. In order to finish up my "quota" of push ups, I set my knees on the ground and do it like that.
I was wondering if this by any chance is
ruining the idea of the whole challenge? I am not not a complete beginner tho, I'd say beginner to intermediate.
So far I haven't done nay rest days, should I take every 5th/7th or 10th day as a rest day?
