The technique-integrity layer around your speed training: log what the radar says, track your block, and verify the swing held while the number climbed. We never estimate mph from video.
Read-only demo — logging is disabled.

No core-control screen on file. TPI recommends passing pelvic tilt or seated trunk rotation (plus no pain) before dedicated overspeed blocks; the Stack philosophy manages intensity through intent ladders instead. Advisory either way — take the 2-minute screen to light this up. Take the screen
No readings yet. Enter what your radar says — we don't guess speed from video. Log a driver reading and the trend starts here.

No vertical jump on file yet. It's a two-minute test in the Movement Screen — log it once and the triage runs from your real numbers.
