Product Details

Our manufacturing process is as meticulous as it is innovative. Using a photo you provide, we capture 16 exact hand measurements with our own custom-built software. Combined with our algorithms, the process has been refined for more than a decade, this creates a production file tailored to your unique hand shape. The result is an ergonomic fit with a precision deviation of less than 0.2 cm — essential for delivering optimal stimulation across all four fingers while lowering the risk of injury through proper finger positioning. 

The friction-free, ergonomic fit around each finger minimizes pain from small edge training and ensures maximum muscle engagement during the final phase of each contraction, rather than relying on skin friction.

Each device is 3D printed, hand-assembled with metal rods, industrial adhesives, and power tools, and then shipped from our production partner in Austria. We use carbon fiber reinforced PETG and steel rods to build a gripper that’s exceptionally durable. While they’re not made for direct impact, we’ve yet to see one break during a training session. The ideal use is with a pulley system or the bumper addon. 

No maintenance is required — it’s made to work, and keep working.

Each gripper is individually made, assembly is by hand, minor imperfections may occur as well as minor changes to design layout and colours. 

Grip Gains

The Grip Gains app is a comprehensive training system that implements the complete protocol David developed over a decade to break through his performance plateau. Unlike conventional training apps that function as digital logbooks with generic templates, this application embodies sophisticated mathematical models that analyze your performance data, prescribe individualized workouts, and continuously adapt to your progress.

The app handles all complexity behind the scenes, providing simple one-click training sessions while managing load prescription, volume, duration, and progression based on your individual force curve. It represents the digital evolution of the increasingly sophisticated algorithms David used to track every training session over 10 years.
