Ask HN: Reliable and scientific exercise guide/program
There are enough scientific proof and personal experience showing while I'm losing muscle it starts getting harder and harder to sit and work. Back pain, shoulder pain, etc. no matter how correct I sit/stand.
I hate gym and exercising (even though I used to be a serious gymnast between ages 9-18) but there's no choice but to be active and build enough muscle, otherwise, I can't continue sitting and doing the work I love for long hours.
I'm looking for a reliable, trustworthy, and scientific guide or program for building muscle. I'm not necessarily looking for motivation or coaching, just a proven program that helps me gain and maintain enough muscle to stay healthy. Also, it doesn't need to be an app.
