it would take some breaking - rubber band type thing, water proof etc
Be a little careful. The oh had one and it got put in the draw when we had a few functions lined up and forgotten. I came across it the other day and the band was cracked near the body as if you had tried to put it on backwards. It was two years old I guess.
They way you are talking it would appear you have other thrusts to be measuring though, not sure if it would adjust small enough for you but at least it will help with stamina if it does. Remove when it goes purple.
Edit: oh, forgot to add: an Apple Watch is best for this use as you can call yourself at the appropriate moment to help things along, it has a handy vibrate function.
