PBT->VBT Converter
How it works
- Select the desired exercise by clicking on the dropdown box.
- Enter your prescription based on percentages (Sets, %RM and Reps).
- Your equivalent VBT prescription will appear below: set your encoder to the Target Velocity shown and use the Velocity Loss Cutoff to stop each set.

Velocity Loss Cutoff

As long as you stay within approximately ±0.04 m/s of the target velocity, you will be working at the desired intensity. If you go outside this range, adjust the load up or down. A range of ±0.04 m/s is acceptable — 0.08 m/s corresponds to roughly 5% RM in most exercises.

Formulas & References
- The "Max Number of Reps" is based on Brzycki's formula.
- The velocity loss tables used are from González-Badillo et al., 2021.
- The squat velocity loss table is applied to all lower body exercises, and the bench press table for upper body.
- Calculated velocity loss is more accurate for squat and bench press.
- Always round down the velocity loss result obtained.
- The value of velocity loss is indicative, especially for exercises not studied by science. If fatigue is excessive, reduce by 5-10%.
