It's exhilarating. That's why I do it. I posted something to instagram [video] because I had a yoga instructor on my feed that inspired me (if this guy posts his stuff for thousands of likes, why can't I?) and have occasionally shown things off since. But I much prefer to have a broad chest and to bust out handstand push-ups in person than posting to social media. I only post a physical show-off once every six months or so. But that's because I have an aversion to preening and humble bragging--or just regular bragging--on social media that a lot of my peers obviously do not. But klein is on the money. I'm broke, I was athletically inclined growing up, so working out is a hobby that comes easy to me. It also comes with hard-to-fake results which signal to those around me that I have self-discipline and physical health. It's a much better hobby than video games (no offense meant). And the "side-benefit" is a healthier, leaner, more robustly immuned body that will stick around for my kids' kids. But I can't help but feel that the main purpose fulfilled by my behavior is enhancing the presentation of this body we call Max. Although, it's also really fun. It took me six weeks of practicing every day to be able to do a handstand push-up. And now busting one out is a joy.
