🎯 What Is Velocity Based Training (VBT)?
Velocity Based Training (VBT) is a modern training method, where load (weight, number of sets and reps) is regulated by barbell movement velocity measured in real time. Instead of subjective RPE ("how I feel"), objective velocity data.
The foundation of VBT is a strong inverse relationship between weight (% 1RM) and velocity. The heavier the weight, the slower it moves. This relationship is so stable that velocity can accurately determine % 1RM without maximal testing. For example, if the bench press barbell moves at 0,50 m/s, this corresponds to ~80% 1RM.
VBT uses linear encoders (ten-centimeter sensors) or accelerometers, which measure barbell velocity. The most popular systems: GymAware, Tendo Unit, Beast Sensor, PUSH Band. Data are displayed on a phone or tablet in real time.
The main advantage of VBT is autoregulation. If you are tired today, velocity will be lower — VBT automatically reduces the load. If you feel great, velocity is higher — the load is increased accordingly. This allows training at optimal intensity every day.
📋 How to Perform?
Velocity zones and their application:
| Velocity Zone (m/s) | % 1RM (Approximately) | Training Goal | Repetitions |
|---|---|---|---|
| >1,00 m/s | 30-50% | Speed and explosive power | 5-8 |
| 0,75-1,00 m/s | 50-70% | Power — optimal zone | 3-6 |
| 0,50-0,75 m/s | 70-85% | Hypertrophy and strength foundation | 6-12 |
| 0,30-0,50 m/s | 85-90% | Maximum strength | 3-5 |
| <0,30 m/s | 90-100% | Absolute strength (approaching 1RM) | 1-3 |
⚖️ Pros and Cons
| ✅ Pros | ❌ Cons |
|---|---|
| Objective load management (not subjective RPE) | overview |
| Autoregulation — load according to daily condition | Need to learn how to use the technology |
| 1RM can be determined without maximal testing | Measurement accuracy depends on the equipment |
| Reduces risk of burnout | Additional time for data analysis |
| Allows precise programming of load | Not all exercises are suitable (isolation exercises) |
| Suitable for strength, power, and hypertrophy | Too complex for beginners |
🔬 Scientific Research
Scientific Research on VBT:
- Gonzalez-Badillo & Sanchez-Medina (2010) — a stable linear relationship between velocity and % 1RM was established.
- — the VBT group achieved 8% greater strength gains than the RPE group.
- — a 20% velocity loss limit is optimal for hypertrophy and strength.
- — VBT allows accurate prediction of 1RM without maximal testing.
- — VBT reduces the risk of burnout compared with traditional methods.
💡 Practical Tips
- Start with the main exercises — squat, bench press, deadlift are best suited to VBT.
- Determine your velocity profile — separately for each exercise. The velocity-%1RM relationship differs.
- Use a 20% velocity loss limit — this is the optimal threshold for most goals.
- Don't forget technique — the pursuit of speed must not compromise technique.
- Combine VBT with Periodization — different velocity zones for different phases.
- Track Trends, Not Individual Numbers — velocity dynamics over weeks are important.
- VBT + Cluster Sets — a golden combination for developing strength and power.
🙋 Frequently Asked Questions
Does VBT Replace Traditional 1RM Testing?
Partly. Velocity can accurately predict 1RM, but it must be periodically verified with maximal testing.
What Equipment Is Required?
A linear encoder (GymAware ~1500 EUR, Tendo ~800 EUR) or an accelerometer (Beast Sensor, PUSH Band ~200-400 EUR).
Is VBT Suitable for Beginners?
It may be too complex. Beginners should focus on technique and fundamental principles.
Can VBT Be Done Without Equipment?
Video analysis can be used (filming and timing), but it is less accurate and not in real time.
