Bands and Chains Wreck Your VBT Velocity Readings: How to Fix It
Add bands or chains and your velocity zones lie. See why accommodating resistance skews VBT readings, and how to test and prescribe around it.
Bluetooth Dropout Losing VBT Reps Mid-Set: How to Diagnose and Fix It
A set logs 4 of 6 reps and the velocity chart has a gap. Split the cause into interference, distance and buffering, then recover the missing data.
Clean and Jerk Dip-Drive Velocity Tracking: Is It a Depth Problem or a Timing Problem?
A missed jerk can come from a shallow dip or a slow reversal — the bar trace looks the same either way. Track transition velocity to tell them apart.
How to Track Kettlebell Swing Velocity and Power with an IMU Sensor
Kettlebell swing velocity depends on where you mount the IMU: bell, wrist, or hip. Placement protocols, load benchmarks, and 2 cited studies.
How Tempo-Prescribed Reps Distort Your Velocity Zones and How to Fix the Reading
A 3-1-1 squat reads 0.29 m/s at 80% 1RM, right in the 90-100% zone. Learn why paused and slow-eccentric tempos distort velocity zones, and how to re-profile.
Why Your Second Set Is Faster Than Your First: PAP or Sensor Warm-Up Artifact?
Your second set reads faster than your first at the same load. Real potentiation, or a sensor still warming up? Here is how to tell the two apart.
Jerk Dip-and-Drive: Testing Velocity Consistency Rep to Rep
Same load, same lifter, different rep — dip depth shifts and drive velocity drops. The rep-to-rep testing protocol, CV% thresholds, and what to fix first.
Fixing Bar Velocity Spikes From Bouncing: How to Spot and Filter the Artifact
A single rep reads 1.4 m/s and wrecks your average. Learn why bounced reps and bar drops spike bar velocity readings, and how to filter the artifact out.
Fixing Deadlift Velocity Shifts From Grip Style: Standardizing Hook, Mixed and Strap Pulls
Switch from straps to hook grip and initial pull velocity jumps 15%? That is grip mechanics, not new strength. Here is how to standardize the reading.
Estimated 1RM Keeps Changing Daily: Is It Noise or Real Readiness Drift?
Your velocity 1RM swings 8kg between sessions with nothing changed. Separate measurement noise from real readiness drift and build a stable baseline.
When Smith Machine Counterweights Skew Velocity Readings: How to Correct for the True Effective Load
A counterbalanced Smith machine quietly subtracts kilograms from your real load. Learn to measure the offset and stop it from wrecking your velocity zones.
When Two VBT Devices Disagree: Reconciling Velocity Readings
LPT says 0.52 m/s, IMU says 0.61 m/s on the same rep. Here is the cross-check protocol to find out which device to trust before you make a training call.
