edited outBelow is my pushups report sheet that I will be recording everyday in my notebook. I'm very happy to be part of this experience
That looks good. Each row of my chart has 5 slots for up to 5 pushup sets per day, and if I do more than 5 pushup sets in a day then I add another row for that day,. and so I label each of my pushup sets with the time that I did the set, and how many seconds it took me to do each of the pushup sets.
The idea of recording ones daily pushups maybe for reference in future seem to be a very nice one generally,however using pen on paper could be prone to errors like the idea of adding more columns on a row section (just as you mentioned) whenever there's an increase in the total sets done for that particular row(usually a day) which is a bright one actually, with pencil there's still a chance of erasing it but later it will still get rough (and that's even if the end of margin hasn't be reached), with pen it's far worse but with a digital hosted spreadsheet then everything can be done smoothly. There's no really need for PC there are many a lot of software for mobiles to perform them so anyone thinking of doing such can always use the software(which more easier and neater).
