Yep, adjust as needed. Repeat weeks, change groups, change type of push-ups, whatever. At the end of the 6 weeks, we'll decide if we want to start another 6 week spreadsheet and try again.
I could probably get through 100 wall pushups right now, but I want to strive for more full body core work so I'm in Group 1 and won't make 100. But I'll fer darn sure see a lot of improvement in 6 weeks no matter what.
