I'm very heartened by the numerous replies and encouragement to do some pushups.
A friend of mine is a personal trainer, I'll be seeing her next week and will ask her to show me how to do both push ups and sit ups (the former I really can't do while the later I end up moving in a walrus lurching style from one end of a hall or room to the other and look very dorky doing too)
I have a walking app to track my daily walking (usually a min 1½ - 2 miles (2 - 3Klm) per day) so push ups might become a thing I do, too. (Just as an aside, I got advised to "walk up all flights of stairs briskly" for a very short burst of exercise which I've been doing for close to twelve months now).
I was encouraged by this thread and took up the challenge 59 days ago which is unique for me. I also use stairs to go up though up to 3-5 floors. During this period I have lost about 8 kg weight which is different stamina for my body. I do 4-5 sets of pushups every day and spread them throughout the day and about 20 pushups per set. Even I take home made food while in office. I am trying to be health conscious by following this thread
I used to enter the number of daily pushups in my excell sheet but in the middle I did not keep a regular account then a total number of pushups based on guesswork should be reported in this thread.
My total number of pushups in 59 days - 2500 (approx). I hope to continue my pushup until the price of BTC reaches $100k
