This uses mediapipe AI vision to detect when the player has proper plank form (knees-hips-shoulders in a horizontal line, elbows low)

Also using threejs for visuals and tonejs for audio

It runs in real-time in the browser, using a regular laptop + webcam

You can track chin-ups, push-ups, or planks. I will continue to add more exercises into the game

Any feedback would be appreciated!
