As the main purpose of the forum is to improve fitness, would it be okay for contributors to add links to YouTube channels?
As long as it is in the best interests of forum members and not just pure self-promotion, I don’t see a problem with this. If it starts to get spammy, we may need to look again, but until then, fire away and post your YouTube channel URLs.
FitnessBlender, Athlean-X, Yoga with Adriene, Jeff Nippard, and Pamela Reif are popular YouTube Channels for training videos.
