Why Deadlift Floor Slack Corrupts Your First-Pull VBT Reading
Deadlift floor slack inflates first-pull velocity before real resistance kicks in. Here's the setup routine that filters the fake reading out for good.
How to Fix a Poor-Fit Load-Velocity Regression When R² Is Low
A scattered load-velocity chart usually means a narrow load span, thin trial count, or an outlier — not bad luck. Diagnose it and rebuild a line you trust.
Why the First Warm-Up Rep's Velocity Is Noisy and Should Be Cut From Your Load-Velocity Regression
The opening warm-up rep runs slower than rep two or three. Here is the neuromuscular reason, the data behind it, and how to fix your load-velocity line.
Why VBT Sensors Misread Smith Machines, Cables, and Plate-Loaded Equipment
A Smith rack, cable stack, or plate-loaded machine changes what your VBT sensor measures, not just where it sits. Why readings drift, and how to fix it.
Hip Thrust Load-Velocity Profile: Testing From 30% to 85%
Hip thrust velocity doesn't scale with load like squats do; 30-50% 1RM sets move noticeably faster. See the 30-85% testing protocol and 1RM estimation.
Load-Velocity Profiling for Weighted Pull-Ups: A Practical Build Guide
Stuck guessing pull-up loading? Build a load-velocity profile in one session and stop grinding sets never meant to be maximal.
Velocity-Based 1RM Prediction Accuracy: How Error Varies by Exercise
Squat SEE is 3.9-6.2 kg; deadlift is 8.3-14.5 kg. See the 10-exercise CV% and ICC table, plus the 5-step protocol that keeps error under 4%.
Hex Bar Deadlift Load-Velocity Profiling: A Complete VBT Guide for Maximal Power Output
Hex bar deadlifts move 21% faster than straight bar deadlifts at the same load, which changes your velocity zones. See the testing protocol and V-L curve.
Why Monitor Load-Velocity Every Session: Daily Variability and the Case for Autoregulation
Your 1RM can swing 18% day to day. Load-velocity monitoring every session catches that shift before autoregulation math goes wrong. Here's the proof.
How to Calculate Estimated 1RM from Velocity Data
Mean velocity correlates with relative load at r=0.97, accurate enough to skip max-effort testing. Here's the step-by-step estimation protocol and formula.
How to Create a Load-Velocity Profile: Practical Guide
Guessing your 1RM from a chart is unreliable. Build a profile with the right test loads, read the regression line, and auto-regulate load every session.
Force-Velocity Deficit Diagnosis and Correction: Practical Guide
Weak jump but strong squat? That mismatch signals a force or velocity deficit. This profiling protocol sets thresholds and a correction plan to fix it.
