Hey sit down and listen to the advice of the fart man because he is the master of fitness.
People who do sports and research for a few months ...
Another subnormal who thinks he's smart. To my ignore list you go.
Just push-ups is kinda pointless, there are more muscle groups in your body. Add pull-ups, dips and crunches and you cover the basics of core strength. It's great for your body, and still has nothing to do with the price of Bitcoin.
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.
