Gpath is an intelligent strength training system that combines a compact external device with a mobile app. The handheld sensor captures real-time movement velocity during each repetition, enabling Velocity-Based Training (VBT) methods to be applied with precision. This data unlocks two key levels of feedback to help you train smarter and build muscle more effectively over time.
The first layer is real-time feedback during your workouts. The app delivers subtle, immediate signals—visual, auditory, or both—that encourage optimal performance. Whether it’s subconsciously prompting faster movement in the concentric phase or promoting control during the eccentric, these cues are designed to reinforce the most effective training behaviors. Over time, this consistent feedback leads to better form, more powerful reps, and improved muscle gains.

The second layer is training optimization based on session-wide data. Gpath tracks your effort, training history, and even your estimated muscle recovery, using this information to tailor your next workout. This helps maximize your strength progression while avoiding burnout or ineffective load choices. The sensor’s precise velocity data gives us an advantage over other training apps—it allows us to calculate exactly how well you executed each rep, and how your training should evolve from there.
Gpath is grounded in scientific research and built for real-world performance. It transforms subjective training into a data-driven process that adapts to you—rep by rep, set by set.
Gpath captures a wide range of training data to provide users with meaningful feedback, guide performance improvements, and ensure consistent device operation. The system continuously tracks key movement and performance metrics during every workout, translating raw motion into actionable insights.
As you exercise, Gpath measures your movement velocity in real time, allowing for detailed analysis based on the principles of Velocity-Based Training (VBT). It recognizes and times the different phases of each repetition—specifically the concentric (lifting) and eccentric (lowering) segments—offering insights into pacing and control. The device also tracks the total distance covered during each movement, giving additional context to your effort and execution. Using these measurements, Gpath automatically counts repetitions and evaluates whether they meet quality standards, ensuring that only valid reps contribute to your workout data.
To deliver the most precise feedback possible, Gpath calculates a set of advanced performance metrics during every rep:
These measurements give both athletes and coaches an in-depth understanding of movement quality, effort, and technical execution. Whether you’re training for strength, speed, or hypertrophy, this data helps tailor and refine your approach.
| Metric | Detailed Definition | Movement Phase | Impact on Training |
|---|---|---|---|
| Mean Velocity | The average velocity across the entire movement phase, typically during the concentric (lifting) part of the rep. It shows how fast you move overall. | Concentric | Affects load estimation; used to prescribe and evaluate effort levels. |
| Propulsive Velocity | The average velocity during the portion of the concentric phase where acceleration is greater than gravity. Reflects the explosive part of the lift. | Concentric (active phase) | Indicates neuromuscular explosiveness; helps guide power and speed development. |
| Eccentric Mean Velocity | Average speed while lowering the weight. Helps assess control, stability, and time under tension during eccentric loading. | Eccentric (lowering) | Useful for hypertrophy and technique refinement; slower values = better control. |
| Acceleration | The rate of change in velocity during the beginning of the lift. Shows how quickly force is being applied to start the movement. | Early Concentric | Important for strength and power profiling; high values show fast force onset. |
| Power | Total work output over time, calculated as force × velocity. Indicates how much energy is being transferred during movement. | Entire repetition (focus on concentric) | Key metric for athletic performance and explosive strength. |
Beyond performance tracking, Gpath actively monitors the health and operational status of the device itself. It checks battery levels and alerts you when charging is needed, so you’re never caught off guard during a session. The system maintains a constant check on Bluetooth connectivity to ensure smooth communication with the app, and it automatically calibrates the sensor to maintain accuracy and stability throughout your workouts.
To uphold data integrity, Gpath includes advanced noise filtering and validation mechanisms. These systems help distinguish clean, meaningful motion data from random spikes or environmental interference.
By combining precise movement tracking, intelligent device monitoring, and rigorous data validation, Gpath ensures every rep is measured accurately and every training decision is backed by reliable, high-quality information.
Accurate motion tracking with the Gpath device depends on proper sensor placement. Because the device can be used across various types of exercises and equipment, it’s important to understand how to correctly position it in each context. Below, you’ll find practical guidance based on the training setup you’re using.
For barbell-based exercises, the sensor should be mounted using the dedicated attachment included with your order. The semicircular part of the attachment should be secured tightly to the barbell itself. Once in place, the Gpath sensor can be magnetically connected to this attachment. To avoid interference during your lift, it’s recommended to attach the sensor where it won’t obstruct your grip or movement.

When training with dumbbells or kettlebells, we currently do not provide a dedicated mounting accessory. However, a compatible solution is in development and will soon be available. In the meantime, it’s essential to ensure the sensor is magnetically secured in a stable location on the dumbbell—ideally a flat surface—so that it doesn’t shift or detach during movement. A helpful tip is to hold the dumbbell still for about one second before starting your lift. This allows the sensor to stabilize and optimize data tracking. If the device fails to register movement, switching to the “high sensitivity” mode in the app may resolve the issue.
For exercises performed on weight-stack machines, the placement is more straightforward. The sensor should be placed directly on the moving stack of weights, ensuring it travels with the load during each repetition. This guarantees consistent and clean movement data.
When using plate-loaded machines or those with free-weight mechanisms, the motion paths can vary more significantly. In these cases, the best practice is to attach the sensor to the part of the machine where the movement is most linear and vertical—typically the component that travels the furthest distance upward. This will yield the clearest signal and most reliable tracking.
Currently, Gpath does not support bodyweight exercises. While future development may introduce compatibility or accessories for these movements, for now the focus remains on external-load-based resistance training.
By following these placement guidelines, you ensure the Gpath system can accurately track your motion, measure performance, and deliver data you can trust to guide your strength progress.

To maximize the benefits of Gpath’s real-time feedback system, we offer a dedicated phone mounting solution designed specifically for gym environments. This visual feedback has been shown to significantly enhance training outcomes by allowing users to monitor their velocity and movement cues during each rep—without disrupting their flow.
The phone mounting set consists of two parts: a thin adhesive metal plate that you attach to the back of your phone (or phone case), and a strong magnetic holder. The magnetic holder can be secured to any stable metal surface—such as the frame of a weight machine, squat rack, or lifting station. Once mounted, your phone will attach securely to the magnet, staying visible and accessible throughout your workout.
This setup ensures the screen is always in view without interfering with your movements or creating any safety risk. It allows you to glance at key feedback—like velocity, rep quality, or training cues—while keeping your focus on performance.
By using the visual feedback system as intended, you gain a deeper connection between movement and data, reinforcing good technique and encouraging more effective, goal-driven training.

Training with Gpath is designed to enhance your strength development through precision, feedback, and intelligent data interpretation—without interrupting the natural flow of your workout. By combining a compact, sensor-equipped device with a smart mobile app, Gpath transforms traditional strength training into a performance-optimized experience.
Once attached to your equipment, whether it’s a barbell, machine, or dumbbell, the Gpath sensor tracks key movement metrics like velocity, range of motion, and quality of execution in real time. As you train, the app delivers immediate feedback designed to improve performance. For example, subtle visual cues or sound prompts can help you maximize explosive power during the concentric phase or maintain control during the eccentric phase, all while reinforcing proper technique.
Each repetition you perform is automatically recorded and evaluated. Valid reps are counted, and their quality is assessed using our Gpath Perceived Effort (GPE) scoring system. This score forms the foundation for post-workout analysis and intelligent progression planning. Based on your GPE and other performance metrics, the system adjusts your next workout by recommending smarter loads, rep schemes, or even rest intervals—ensuring that every session builds directly on your progress.
To achieve the most accurate results and the full benefits of Gpath’s tracking system, each repetition should be performed as quickly and explosively as possible. Executing reps with maximum intent allows the sensor to capture objective, high-fidelity data—minimizing tracking gaps and delivering precise insight into how well you completed the movement. This, in turn, enables the system to suggest the most accurate and effective optimization for your next workout.
You don’t need to guess how hard to train or when to push. Gpath handles the details, so you can stay focused on lifting. Whether you’re chasing a personal best or simply refining your form, training with Gpath means your workouts are always informed, adaptive, and goal-oriented.
