Practice Yoga at Home Without a Teacher — Just Your Camera

A yoga class costs $20-30 per session. A private teacher costs $80-150 per hour. Or you can follow a YouTube video alone and wonder if you're doing it right.

There's a middle option: your phone camera detects 33 body landmarks and shows you your alignment data in real-time. Not a replacement for a teacher — but a tool for the 29 days a month you're practicing alone.

What your camera can see

33 body points: both shoulders, elbows, wrists, hips, knees, ankles, and more. From these, the app calculates joint angles, body line alignment, and symmetry between left and right sides.

In Downward Dog, it can show you: is your hip angle at the ideal 60-80° inverted V? Are your arms fully extended? Are your knees straight or still bent?

What your camera can't see

It can't feel your breath. It can't sense whether you're gripping your toes or spreading them. It can't know if your shoulders are relaxed or tense. The internal experience of yoga is yours — data just handles the external geometry.

How to set up

Place your phone 6-8 feet away, at hip height if possible. Make sure your full body is visible. Good lighting helps — natural light is best. Wear form-fitting clothes so the camera can see your joints clearly.

Then just practice. The data is there when you want it. Ignore it when you want to be present. Both are valid ways to use the tool.
