From the reviews

Hidden Terms in Promotions – Unethical Policy I loved the yoga classes, the variety of teachers, and the convenient schedule. However, their promotional policy is misleading and unethical.

★★★★☆ — Elena, Feb 2025

My very favorite studio in the city. Beautiful space -- huge windows that look out over beautiful green trees. Skylight that brings in natural light. Heated vinyasa yoga with wonderful teachers and great music. I've made some of my closest friends from the studio; very nice crowd.

★★★★★ — Lydia, Dec 2022

Had a great heated session at this mornings 9am Vinyasa yoga class! Really enjoyed it, I am a beginner and I felt very comfortable with my level. The teacher was very good and friendly. I liked the music a lot too. The classroom is very beautiful and it’s on the top floor between trees so it feels very zen.

★★★★★ — Jo, Jan 2025

I attended the studio for over 3 months. Overall, I enjoyed the yoga classes and the quality of the teachers are quite balanced. There are a few factors that made me give them 4 stars instead of 5. 1. The music is usually very loud and distracting. The loud music really diminished the purpose of doing yoga. 2.

Your first hot yoga class at Yoga Flow SF - Union

Nervous about your first hot class? Almost everyone is, and a good studio expects beginners to walk in the door. Here's what to know. What to expect: the room is heated, so it feels intense for the first few minutes — rest in child's pose any time you need to, no one will bat an eye. Hydrate: drink water through the day before class, not just as you arrive, and bring a bottle. What to bring: a mat and towel, water, and a change of clothes; wear something light you don't mind sweating through, and skip a heavy meal in the couple of hours beforehand. Arrive 10–15 minutes early to sign in and set up. It gets easier fast — most people say their third class feels completely different from their first.

Heat and intense exercise aren't right for everyone — if you're pregnant or have heart, blood-pressure, or other health concerns, check with a doctor before your first hot class.
