What Is Velocity-Based Training?
Velocity-based training (VBT) uses bar speed to objectively measure training intensity and fatigue. Instead of relying solely on percentages or RPE, you track how fast you move the barbell. As you fatigue within a set, bar speed drops — once it falls below a threshold (velocity loss cutoff), you stop the set. This autoregulates volume per set and prevents excessive fatigue accumulation. Different speed zones correspond to different training adaptations: maximal strength lives below 0.35 m/s, while speed and power work happens above 0.8 m/s. A velocity-based approach helps you train at the right intensity on any given day, regardless of how you feel subjectively.
