Velocity-Based Training (VBT)

Stop prescribing percentages of a hypothetical 1RM.

Daily readiness fluctuates by up to 18%. Prescribing a strict 85% of an old 1RM will inevitably lead to overtraining on a bad day or undertraining on a good one. Velocity-Based Training (VBT) solves this.

TraitVelocity Zone (m/s)Target Adaptation
Absolute Strength< 0.50Maximal Force production
Accelerative Strength0.50 - 0.75Force at high loads
Strength-Speed0.75 - 1.00Power output

Use our 1RM Velocity Estimator to track daily readiness without maximal testing.
