Monitor, profile, and assess athletes on and off the barbell with our suite of VBT measurements in our device. Validated against gold standards, our portable system offers unrivalled flexibility and speed of testing.

With Output, we make VBT simple with a state of the art wireless sensor which attaches to the barbell, kettlebell, trap-bar and wrist. It also brings a new level of accuracy versus traditional options like Push Band or Beast Sensor.
Simply pair up and select your target velocity zone in the Capture app to get started with VBT!
You can get more information on this feature on our knowledge base.
Instant feedback to athletes on key metrics (mean / peak velocity) creates focus and intent
In set velocity targets for athletes to stay on track with the session goal
Real-time leaderboards for VBT drives weight room competition
Automated load-velocity profiling detects when athletes are above and below their baseline
Velocity drop-off can manage fatigue and desired adaptation (strength, speed or hypertophy)

Build a load-velocity profile in an instant, without the need for manual data entry or spreadsheets. Output stores an athlete's VBT training data automatically, allowing automatic load-velocity profile generation
Build a load-velocity profile with your data in seconds
Estimate 1RM based on minimum velocity thresholds
Identify optimal loading for peak power
Use as a rehab-assessment tool to sub-maximally quantify progress in power and strength
Combine with our vertical jump testing data to understand your athletes' power qualities.

Velocity based training systems vary hugely in cost, popular camera-based and linear-positional-transducers cost over $2000 per device.
Many more cost effective VBT options also exist with Output Sports sensors being under $500 per device.
Like Output Sports, most systems also require a software subscription which vary on price based on feature-set and the number of athletes you work with.
Velocity based training quantifies weight room S&C in more detail than reps and sets based training only. The velocity, power, force and displacement data can be used to drive focus and competition with the athletes.
Some research indicates improvements in strength, acute force production and power (6-12%) when subjects are provided visual feedback (1,2,3).
You can use multiple racks or stations - If you have 10 training stations used by 30-40 athletes, set up 10 racks with a sensor at each one. This allows you to work with smaller groups of 3-4 athletes per station. With this you can also do supersets, or combine VBT and other exercises like jumps, power, or mobility, having athletes alternate with each other to keep the flow moving.
Output data is very reliable, in multiple tests it gives similar readings as other highly-respected brands in the market. You can read more about it here.
Start simple. Just focus on moving the bar as intentfully as you can and tracking the speed. If you need help being intentional, think of using each of your reps to beat the speed of the previous one. It gives every move you make an explicit intention.
Strap the sensor on and do a few sets of an exercise like the squat. Try to move the bar faster on each rep and see how the velocity changes.
If you're new to VBT, you can also start with one of our predefined velocity zones. Choose a zone like "Light Loaded Power” or "General Strength" and autoregulate your weight based on hitting that target velocity. You can read more about it here
The key is to get comfortable with the concept of moving with intent and seeing how the velocity changes. Don't overcomplicate it at first. Just focus on the basics of VBT.
We tested all the velocity-based training devices out in the market right now, and make recommendations taking into account your specific needs. You can read more about it here.
The different types of technology used in VBT measurement are: linear positional transducers (LPTs), inertial measurement units (IMUs), camera-based systems, and mobile apps.
Our IMU-based system provides unmatched versatility, covering traditional barbell lifts, Olympic lifts, plyometrics, med-ball throws, mobility assessments, and more, with a strong commitment to continuous innovation, an intuitive user experience, and a leading cloud platform.
VBT is a way to monitor an athlete’s readiness and ability to train via barbell velocity. If the bar is moving quickly, then the athlete’s readiness to train is high, and/or the load applied to the exercise is too low. If the bar is moving slowly, then readiness to train is low and/or the load is too high. Some VBT use-cases are: load-velocity profiling; targeting specific adaptations in training; driving intent in the weight room.
You will need your barbell, trap-bar and/or dumbbells, to train with and then to quantify your weight-training, you will also need one Output V2sensor, which straps to your bar or wrist and pairs to the Output Capture mobile/tablet app.
