100% this. I’ve been physically active for my entire life, but I’ve also suffered from postural issues for the past 5 or so years, which I ascribe to a combination of: - extended sitting due to long days at the office - a weights routine that compounded the problem with muscular imbalances. I was stretching regularly too - but that doesn’t help if you’ve “lost” the feeling of what’s normal, and what muscles should be used during certain movements. I’ve regained most of it now, but that’s after years of experimentation to rediscover what muscles weren’t working. Retraining is definitely necessary if you’ve lost it.
