I am a BMX rider and core strength training is very important to improve my performance. But the traditional core strength training methods, such as sit-ups and planks, are so boring. So I want to use micro:bit to make core strength training much fun.

1. I spent a lot of time on how to use the radio to synchronize two micro:bits. Despite this, they are still not 100% correct and error still happens very occasionally 2. How to detect vibration also took me a lot of time. I use the accelerometer first, but finally I chose sound sensor

If I had more time, I'd like the micro:bit to log reaction times. This data can show whether my left and right sides are balanced. I also hope to connect three or more micro:bits together via radio. That will allow me to do more interesting training
