I want to share this thou it might sound funny, I normally hit the 100 pushups in two sets 50 in the morning 50 in the night before going bed, but each 50 is in two sets 25, 25, and sometimes there will be an addition, then this evening dosage wasn't that easy for me I managed to hit the first 25 successfully getting to the remaining 25 I was only able to do 15 and paused, thereafter lizy my wife came in and was like honey what is the problem of course I told is remaining 10 to complete my dosage, to my greatest surprise Lizy completed the remaining 10 dose for me, and when I asked her how was she able to do it like she has doing it before and she said yes that she has been practicing behind my back we laughed and was like the 100 pushups challenge has become parts family business.
