Gyroscopic neuromuscular training
One Continuous Challenge.
Spinweight is a handheld, gear-driven gyroscopic exercise device. Both hands work together against changing resistance, making coordination part of every moment of the workout.
The movement itself is the challenge. Sense the force, anticipate its direction, and keep both hands coordinated as you build speed and effort.
- Rotor speed
- up to ~10,000 RPM
- Resistance source
- gyroscopic loading
- Input
- two hands, three axes
- Rotor
- 0.5 – 1.5 lb

01 · Origin
Spinweight training came first.
After a motorcycle crash at 19, a traumatic brain injury left me with aphasia, memory difficulties, and mental fog. I could be full of thoughts and still struggle to find the words to connect with another person.
It wasn’t just easier to speak. I could put thoughts into words differently.
About 30 days into intensive, 360-degree bilateral coordination training with gyroscopic resistance, I experienced a distinct shift. A sudden drive to communicate broke through the aphasia like a champagne cork on New Year’s Eve.
Then came a hunger to do things with my hands. Tool use and creativity felt different. My fog began to clear, memories returned, and regulating emotions and communicating became easier.
I taught myself engineering and built and refined dozens of Spinweight prototypes. As I varied my gyroscopic training, I repeatedly noticed corresponding changes in speech, cognition, and coordination. This was a pattern I observed over time, not a conclusion drawn from a single session.
Before Spinweight training, I did not have the movement skills shown here. Afterward, tightrope walking, partner acrobatics, fire dancing, and juggling while standing on an inflatable exercise ball felt naturally accessible to me. I still practiced to develop those skills, but I believe I progressed faster than most because Spinweight training had changed my capacity to learn and coordinate movement.
N=1 These changes happened in me. They motivate the work; independent, controlled studies are needed to establish what Spinweight can do for other people.
02 · The physics, simply
A spinning rotor.
A dumbbell loads your movement through gravity. Spinweight adds gyroscopic resistance: redirecting its spinning rotor produces a turning force that changes with the orientation and speed of your movement.
In cognitive-motor dual-task training, an exercise may be paired with a separate mental task. With Spinweight, the movement supplies the challenge: both hands coordinate through 360-degree cycles, working in opposition 180 degrees apart. Proprioception, prediction, and correction stay part of controlling the load.

Why it gets harder as you go faster
Your coordinated handle cycles drive the rotor through a geared transmission. Redirecting the rotor’s axis requires torque. As you guide the device through its movement pattern, both hands respond to this gyroscopic loading.
τ = I · ωspin · ωprecession
The challenge changes with your pace and movement. Start with controlled coordination, then build effort while maintaining technique.
Coordination under changing resistance
Both hands stay involved as you guide the device through its movement pattern. The workout combines physical effort with continuous sensing, prediction, and correction.
03 · Modular configuration
Configure the device.
Grip, configuration, and pace influence how Spinweight feels and how you train. Start with a configuration and pace suited to your ability and goals.
T-01
Rotor size & weight
Prototype rotor options range from 0.5 to 1.5 lb. Rotor mass and geometry influence the resistance; rotor weight is separate from total device weight.
T-02
Handle size & style
Explore grip diameters and handle styles that suit your hands and the movement you want to train.
T-03
Training goals
Choose a session that fits your goals, from learning controlled coordination to building strength and endurance.
Start with your goals and current ability. Ask about suitable configurations and coaching to develop technique and progress your training.
Prototype ranges. They may change before production.
04 · Training possibilities
Train seated or standing.
Spinweight can be operated from a seated position, including a wheelchair, without using the legs when upper-body function allows. Standing exercise and combinations with other equipment create additional challenges.
Pairs with the rest of the gym
The videos show Spinweight used with a treadmill, stationary bike, and balance equipment. These combinations add demands on posture and stability as the hands coordinate the device. Watch it.
Data
Speed and movement data offer a way to track the mechanical session. Combining those readings with heart rate, VO₂, force, and performance measures would support more informative training comparisons.
Game integration
Spinweight sends motion data to a video game, so your coordination steers an avatar in a race.

Personal results. Early measurements. Questions worth testing.
My experience is the starting point. Mechanical principles, early observations, and research questions each tell a different part of the story.

Precession physics
For ideal steady precession with perpendicular axes, torque magnitude is τ = I·ωs·ωp. Translating that torque into force at the hands requires the device geometry and movement pattern; device-specific measurements are needed to quantify the load.

People learn to control hand-held gyroscopes
The nervous system learns to compensate for gyroscopic torque, and arm configuration is central to how that learning is organized.

Coordination and balance training benefit the brain (general exercise science, not Spinweight-specific)
In older adults, coordination training increased hippocampal volume. Balance training improved memory and spatial cognition without changing cardio fitness. Balance and functional exercise reduced the rate of falls.

Founder's recovery
I experienced improvements in speech, memory, clarity, and emotional regulation after beginning intensive gyroscopic coordination training. After Spinweight training, I found new movement skills felt naturally accessible, and I believe my progress was unusually fast. Repeated changes in my gyro training coincided with changes in speech and cognition. These observations underpin my belief in a causal connection; controlled research is needed to test that connection and determine which effects generalize.

Hypothesis
Coordination as the driver
Can high-complexity bilateral precessional loading produce measurable changes in sensorimotor adaptation, prediction, error correction, or interhemispheric coordination? Studies could combine EEG, EMG, motion tracking, force measurements, cardiovascular intensity, and functional outcomes.
-
Hypothesis
Microgravity
Precession doesn't depend on gravity, so the same resistance should work in microgravity too. That hasn't been tested in spaceflight yet.
