How Tendground works
An evidence-led way to find wellness near you. We map what exists city by city, then add curated picks and bookable retreats carefully, only pointing you to what we would point a friend to.
Every venue, city by city
Sauna, cold plunge, breathwork and recovery studios across 26 US cities, with addresses and official sites. We compile from public listings, so you can confirm the details before you go.
The honest, evidence-based read
What each practice actually does, what the research supports, and what it doesn't. No detox claims, no cure claims, no hype. The guide we wish existed when we started.
Only what we'd send a friend to
As we curate retreats and providers, listing stays free and we never sell placement. We earn a commission only on bookings we actually send a provider.
Wellness writing without the noise.
Most wellness content is either a paid placement or a round-up nobody researched. We map what exists and write the honest version, what the evidence supports and what it doesn't.
No sponsored placements. No pay-to-rank. If it isn't useful, we don't publish it.

Read post →Is a home reformer worth it? An honest buyer's look
Buy a home reformer only if you already practice consistently, learned form in taught classes first, and have the floor space. The break-even against studio classes typically lands around a year for regulars; for beginners the studio is the right first spend.
