A running-gait analysis like the ones in sports labs, from a phone video. Film yourself running from the side, and body tracking measures your cadence, how much you bounce, where your foot lands, your knee at landing, your lean and how even your left and right steps are.
Typical ranges are for recreational distance running at an easy-to-steady pace. Sprinting, hills and very tall or short runners differ.
Checked against simulated runners with known form: cadence, knee angle, lean and bounce come back within a few percent. Camera angle matters most. If you film at a diagonal, distances and angles will be off.
