Practical velocity-based training.
Makes you a stronger lifter and a sharper coach. Everything you need to master VBT in one place: articles, calculators, a free app, and a book.
I've coached with velocity data for over a decade.
Every rep already contains rich data: velocity, range of motion, tempo, bar path. You can’t see most of it without instrumentation; the moment you do instrument, you stop guessing. The cost barrier that kept VBT out of normal gyms is gone. A phone you already own and a free app gets you most of the way there.
Plenty of what gets published about velocity-based training is half-right. Absolute zone charts don’t generalise. Standards depend on context. The five-zone takedown lives in the topic pages and individual articles, where there’s room to do it properly with the research behind it.
What you actually get from VBT, in practice: a more accurate working weight today than yesterday’s plan would have given you, and a real reason to stop a set or push it one further. The bar verifies the intent you trained with, and it reads fatigue and freshness before they quietly cost you a session.
Topics, articles, and calculators.
Topics
VBT has more jargon than it needs. Load-velocity profiling, minimal velocity threshold, eccentric utilisation ratio. The terminology matters because conflating these concepts leads to poor programming decisions. The topics section gives each concept its own page: a plain definition, its boundaries, and links to the articles and calculators that go deeper. Start here when a term comes up in a paper or a coaching conversation and you want to understand it before applying it.
Articles
Long-form pieces on specific programming questions, what the research actually shows and where it falls short, device reviews that name names, and VBT logs from real coaching blocks. Articles are narrow and deep: one scenario, one answer, real numbers. The library covers everything from building your first load-velocity profile to whether the power metrics on your LPT are worth trusting. New pieces ship when something useful is worth saying, not on a schedule.
Calculators
The calculations coaches actually run in the gym: 1RM estimation from a velocity rep, RPE-to-load conversions, warmup plate stacking, load-velocity profile building, max power output. Each tool is built around the specific math that matters for that problem, not a generic formula dropped into a box. Free, runs in the browser, no account required. If you are doing VBT seriously, these save time every single session.
Free velocity-based training app.
Metric is my computer-vision barbell velocity tracking app that runs on the phone you already own. No LPT, no sensor strap, no extra device or additional hardware required. Validated against 3D motion capture and expensive hardware in independent peer-reviewed research. Metric has no cost to start, and no set recording limits with a free coach or athlete profile.
I built VBTcoach because velocity-based training doesn't have to be so complicated or so dogmatic! With the improvement in technology and the expansion of use cases, VBT should be something any coach or lifter can easily pick up and use in their workouts with minimal friction or stress.
I've spent years coaching with velocity data, publishing research, developing app features, and translating it into useful content for coaches and lifters to apply in their training.
Everything on this site (the articles, the calculators, the free guide, the logbook) exists to make velocity-based training practical and accessible regardless of how you train or your chosen tracking technology. So dig in, take what's useful, and put it straight to work. I want you walking away with something that makes your next session better.
I'm writing a book! Pre-order now open
Lifting with Data is in the final stages of editing before publication. It is the most comprehensive guide to velocity-based training and lift tracking there is, putting my 10+ years of coaching and development into a single organized place. We are doing an initial print run of 100 copies by pre-order.
