If in VR, you would have to actually dance.

To do this, you’ll need to harness the power of the Vive Trackers. With two, you can track your feet’s positions (assuming you have a strep to put the trackers on). With a third, you can track your hips (meaning that you can actually crouch and lift your legs, along with other stuff). Three trackers is pretty much near full body tracking to the point that the remaining points are just extra detail.
Four trackers will track your chest’s position. This means you can turn your head, but not your body (since your hips are still being tracked). Five trackers will grant you the ability to place the trackers on your shoulders instead for shoulder tracking. This means you can shrug and have slightly improved arm IK (or basically the system has a better idea where your arms are actually going).
Since you have a Vive, you are already set on compatibility. Each tracker requires an additional USB port (the headset can only track two Vive devices, which are normally your hand controllers), but you can solve this with a cheap but effective Amazon Basic Hub. Furthermore, each tracker costs $99, so for basic tracking, you would need minimally $200, $300 for hip tracking, $400 for full body tracking, and $500 for VR God Mode.
For most other things involving the trackers, High Fidelity released a video awhile back.
