I would add squats to that, but don't say it out loud lest the whiners will soon come and say that you are trolling, that you have no idea about fitness and that what you need to do is join the 100 push-ups a day challenge to experience how that can influence the price of bitcoin.
Well, they forgot about the halving. Put one hand behind your back, then do your push-ups.
I used to do that, but it started hurting my elbow joints. It's kinda heavy.
