Starts itself, works your forearm
Gyropower spins up on its own, no manual flick required. Vellhaven made forearm training as easy as picking it up.
Resistance that scales with effort
The faster the rotor spins, the harder it pushes back. It is a workout that meets you exactly where your energy is.
A minute a day adds up
Short sessions fit into any spare minute of the day. Vellhaven designed it for consistency over intensity.
Our customers say it better than we can
Frequently Asked Questions
How does the self-starting mechanism work?
A quick flick of the wrist gets the internal rotor spinning on its own, so you can start training in seconds.
What does it actually train?
Wrist, forearm, and grip strength, with real cardio-style resistance that increases as the rotor speeds up.
Is it noisy to use?
It runs with a smooth, quiet hum at moderate speeds, comfortable for indoor use.
How long should a session be?
A few minutes a day is plenty; the resistance builds quickly as the rotor speeds up.
Does it come with instructions for starting it?
Yes, getting the rotor spinning takes a few tries at first and quickly becomes second nature.
