Health & Fitness communities, torn down.

Health and fitness communities work best where accountability matters more than information. Training programmes and nutrition guidance are abundant and mostly free; doing them consistently for a year is the hard part, and that is what a good community provides.

This category covers strength training, nutrition coaching, mobility and recovery, sleep, and nervous-system work. The better communities are led by qualified coaches who give individual feedback rather than broadcasting the same plan to everyone. Membership is usually inexpensive relative to one-to-one coaching, which is much of the appeal.

Note that anything touching pharmacology or supplement sourcing sits outside what this index lists, and no community here is a substitute for advice from a doctor who knows your history.
