Good to know you go up to 5 sets in a day, seems you're still very much young and full of energy, life, strength and enthusiasm for you to be doing 5 sets of pushups daily. I would have loved to have same experience of doing 5 sets in a day as well but I spend most of my time in a day at my place of work (office) that is why i choose the convenient time of morning and evening. You are really so devoted in doing this pushups challenge I mean you even take notes of the time it took you to complete each set, wow interesting. Bravo...
I started doing 5 sets per day around 20 days after starting pushups, and I have had to spread the sets out through the whole day, especially in the beginning because I would get sore, and I still get sore.
I started to time my pushups around 50 days after starting pushups because there were questions in regards to quality versus quantity, so I mostly wanted to monitor the timing of my sets in order to get some idea regarding how fast I was going and how consistent I was and also sometimes to purposefully do them fast or slow, depending on how I am feeling or maybe what I am trying to accomplish for any pushup set or any particular day or week.
