Air
Knee-Bend Noise Floor
Stand and drop into a small, repeated knee bend — a vertical oscillation around mid-height, never going deep. Find that threshold by increasing head amplitude in small steps and noting the precise amplitude at which the knee count first slips.
Full Lesson Notes
Complete Practice
Stand and drop into a small, repeated knee bend — a vertical oscillation around mid-height, never going deep. Maintain a fixed rate by silently counting. Now introduce a noise source: deliberately wobble the head left and right at an unrelated rate. Below some threshold of head wobble, the knee oscillation continues cleanly; above it, the rhythm collapses. Find that threshold by increasing head amplitude in small steps and noting the precise amplitude at which the knee count first slips. That amplitude is the noise floor of your lower-body channel. Challenge: The threshold jitters with attention and may not converge to a single value within one session.
