Online coordination exercises
Three exercises for two hands. Learn the movement without a camera, then try a one-minute round with feedback.
Thumb / OK
Show a thumbs-up with one hand and an OK sign with the other. Swap both gestures together while keeping their shapes clear.
View instructionsGun / Goat
Combine two asymmetric signs: a finger gun and a horns sign. Swap them on cue without mixing up your fingers.
View instructionsOpposite circles
Trace circles in opposite directions with your hands. Try to keep both hands moving at the same pace.
View instructionsWhere to start
Start with Thumb / OK: familiar signs with a simultaneous swap. Gun / Goat adds less familiar finger positions. Try Opposite circles if you prefer coordinating movement paths rather than finger shapes.
Prepare for your workout
Each exercise page includes steps, common mistakes and an easier variation. Practise without a timer, then open the app for an interactive round. Camera access is requested only there. Keep the device stable and both hands well lit.
Each round lasts 60 seconds after calibration. Pause or finish whenever you need. The score reflects detected movements in that attempt, not intelligence or health.
