I think anyone who takes selfies of themselves half naked with vanity and pride and self-absorption posting them on Instagram and such are sinning. These celebrities are self-infatuated and it’s not only nauseating but sinful.
meanwhile you have guys like Troy Polamalu who won two super bowls and went to 8 pro bowls. He’s tough, built, athletic... AND ORTHODOX. He prayed on the bench/sidelines, publicly shared his faith and was kind and a good role model. Athleticism and caring about conditioning and training aren’t sinful. What you do with the results can be.
If a bit of pride and occasion excessive self-love is the result of losing 25 lbs, should we instead say fat, get diabetes, and go in and out of hospitals? Should we avoid the gym and turn into Lizzo with our guts bulging as we huff and puff up stairs to stay humble? Nonsense. Lose weight, exercise, pray, and be humble.
