Tell it the weight.
Say how much you are lifting, and the planned voice interface will add it to your workout.
A fitness coach built into your training wear.
Form guidance while you lift.
Demson is developing a sensor-integrated shirt and leggings that count your reps, track your workouts, and provide spoken form cues as you train.
How it works02 / Why Demson
Form can change
as fatigue builds.
As a set progresses, changes in depth, balance, or bracing can be difficult to notice. A personal trainer can provide immediate feedback, but many people train without one.
Demson is designed to give solo lifters a personal-coaching experience: guidance during each set and a record of what they did afterward.
03 / Sensors and coaching
Your movement becomes
coaching feedback.
Fabric sensors measure how the outfit stretches. Software interprets those signals to count reps and identify changes in your movement.
Complete your set.
The outfit is designed to track your movement and count each rep automatically.
Hear the cue.
Your coach will provide brief spoken feedback when it detects a change in your form.
Companion app
Your workouts, recorded for you.
The planned app will save your exercises, weights, sets, and reps. It will also organize your training split so you can review past workouts and see what you trained each day.

04 / The outfit
Designed to train in.
No camera required.
Demson’s planned outfit combines a long-sleeve compression shirt and leggings with integrated fabric stretch sensors. Put it on, connect your earbuds, and start your workout.
The outfit is planned as breathable, fully washable compression wear. Its electronics will use a magnetic charger, similar to the charging connection on a smartwatch.
