Movement sensing / IMU
Motion, in context.
An accelerometer and gyroscope capture how your wrist moves through each set. RYKK uses those signals to build workout context.

A strength training system in development, connecting your goals, your plan and what happens in every workout.
Join Early AccessThe workout itself
A training plan sets the direction. Your workouts show what actually happens. We're building RYKK to connect both — and use that context to guide you toward your training goals.
Exercise / reps / sets
Tempo / rest / effort
Your goals / progress / adaptation
RYKK is being built to connect all three around your training goals.
The RYKK approach
Your goals set the direction. The experience we’re building connects your plan with what happens from one session to the next.
Put on RYKK. It’s designed to stay out of your way.
Focus on the set. RYKK is designed to capture the workout as you move.
Exercises, reps, sets, tempo, rest and heart rate - brought together.
Use each workout to inform the next step toward your goal.
Workout recognition and personalized coaching are in development.
