MooreMuscle.com • Velocity Based Training Series
If you’ve ever had a day where your “planned” weights felt like a max-out… or a day where the same weights flew up like nothing, you’ve experienced the biggest flaw in traditional percentage-based training: your body isn’t a spreadsheet. Velocity Based Training (VBT) solves that by using bar speed to guide training decisions in real time.
VBT uses how fast the bar moves to tell you what load you should use, when to push harder, and when to shut it down—without guessing.
What “Velocity” Means in Strength Training
In VBT, velocity usually means the speed of the barbell during the concentric (lifting) phase, measured in meters per second (m/s). Instead of only tracking weight on the bar, we also track how that weight moves.
Two velocities you’ll hear about
- Mean Velocity (MV): Average bar speed through the concentric phase. (Most useful for programming.)
- Peak Velocity (PV): The fastest instant during the rep. (Useful, but easier to “cheat” with bounce/technique.)
What bar speed tells you
- Readiness: Are you “on” today or fried?
- Intensity: Is this truly heavy for you right now?
- Fatigue: Are reps slowing down as the set goes on?
- Quality: Are you training the intended adaptation (speed vs strength)?
Why Percent-Based Training Breaks Down in the Real World
Percent training assumes your 1RM is stable and predictable day to day. In reality, performance swings for normal reasons: sleep, stress, soreness, nutrition, travel, hydration, pain, and CNS fatigue. When you force the day’s work based on a number you hit weeks ago, one of two things usually happens:
You grind reps that were supposed to be crisp. Technique breaks, fatigue piles up, and recovery gets wrecked.
The load is too light to create the intended stimulus, and you leave progress on the table.
What VBT Does Better: Auto-Regulation Without Guessing
VBT replaces “I think this is the right weight” with “This is moving at the speed we want.” That’s auto-regulation in one sentence.
If your goal is speed-strength and the target zone is 0.70–1.00 m/s, you keep adjusting the bar weight until your reps live in that zone. If the bar slows below it, you’re too heavy for today’s objective.
VBT Zones at a Glance
These zones are commonly used as starting points. Exact numbers vary by lift, athlete, and device—so treat this as a practical guide, not a religion.
| Training Goal | Typical Velocity (m/s) | Typical %1RM (rough) | Best For | Coaching Notes |
|---|---|---|---|---|
|
Speed Pure speed / technique |
1.00–1.30+ | ~30–50% | Bar path, explosiveness, recovery work | Fast reps only. If it slows, the “speed” stimulus is gone. |
|
Speed-Strength Move moderate loads fast |
0.75–1.00 | ~45–65% | Dynamic effort work, rate of force development | Great zone for accommodating resistance (bands/chains) when managed correctly. |
|
Strength-Speed Heavier, still fast intent |
0.50–0.75 | ~60–75% | Power output, strong reps that aren’t grinders | Often where “athletic strength” lives—heavy enough to matter, fast enough to stay crisp. |
|
Max Strength Heavy work |
0.30–0.50 | ~75–85% | Building top-end strength without constant maxing | This is where quality heavy training happens. Stop before reps turn into ugly survival lifts. |
|
Near-Max / Limit Singles & peaking |
0.15–0.30 | ~85–95%+ | Peaking, attempt selection, readiness checks | Use sparingly. Velocity + technique tells the truth about whether a “planned” PR is there today. |
Note: Velocity zones can differ by exercise (squat vs bench vs deadlift) and by athlete. In later parts of this series, we’ll show how to build a personal velocity profile and use velocity loss to manage fatigue.
The Real Reason VBT Works: It Protects the Stimulus
Most lifters don’t fail because they “need more intensity.” They fail because they can’t repeat quality training long enough. VBT helps you train hard and stay consistent by protecting the stimulus of the day:
- Speed day stays fast (instead of turning into a slow, sloppy max-effort session).
- Strength work stays strong (instead of turning into constant grinders that crush recovery).
- Volume stays productive (instead of mindless reps that slow down and beat you up).
If you care about long-term strength, you need a system that adapts to the athlete. VBT doesn’t replace coaching—it gives coaching instant feedback.
What’s Next in Part 2
In Part 2, we’ll get into the science without getting lost in the weeds: the load–velocity relationship, why bar speed predicts strength so well, and how velocity loss can help you manage fatigue and progress faster.
