Instructions

1) You NEED to accept the Health data sharing and updating (two separate screens) to allow the Watch to start a "workout session" to keep recording the accelerometer data during the set. Even when the watch face is turned away from the user.
2) Press "START"
3) Get into the starting position during the 5 seconds countdown
4) Start the set
5) When finished press the "STOP" button
6) Scroll to the bottom
7) Look at the graph and trim the data with the "Ditch last second" button so that the graph ends where the set ended (it is quite intuitive)
8) Enjoy the data
9) "Start new" when ready
