Good lord the reveal at the end seemed mistimed.
No. If you have a skill like Tim's, this is what you use it for.
>My watch takes walking, cycling and running seriously — especially outside rather than on a treadmill — but a hard session at the gym barely registers. It will count my steps for me, but I have to count my own pull-ups

On the flip side, if a user expects too much from a fitness tracker it can lead to unreasonable health anxieties.
A user trying to determine an accurate heart rate or blood oxygen level during exercise (not at rest) will find that the guidelines are too broad and the tracker data is too slow and noisy to get the feedback they want. They can get a rough idea of how hard they exercised and for how long, but a fitness tracker isn't necessary just for that.
