Velocity Based Training (VBT) is one method of auto-regulating training. It can auto-regulate load on the bar, number of reps within a set, total number of sets, any combination of those three, or any other relevant factor in training. It is beyond the scope of this article to make the case for VBT. It’s hard to make a case for VBT when you haven’t first established that the methods used to gauge velocity are valid and/or accurate. VBT has been a training methodology put forth in power athletes and team sports. It has gotten significantly less attention for strength athletes like powerlifting. Other coaches can more appropriately talk on the matter for strength and conditioning outside of powerlifting, and people like Bryan Mann, Carl Valle, Dan Baker, Eamonn Flannigan, and Mladen Jovanovic already have. On the powerlifting side of the house, the volume of writing and academic work is limited to Louis Simmons of Westside Barbell, Brandon Senn of Kabuki Strength, Mladen Jovanovic of Complementary Training, and I guess you could also argue that Mike Tuscherer of Reactive Training Systems as well – although it’s more appropriate to say Mike uses velocity as a reference point, not a driver of training.
