I have been wondering if there is any kind of tech that is wearable that accurately mesaures calories burned, strength output, etc etc for our very specific training?
Everything I have seen is either running or weightlifting, but for example doing a hollow body hold requires no movement, and therefore how would this be measured? Even in a calorific way, as I doubt the heart rate raises much either.
Anyone been using anything?
I can link to some that I have seen if you want more info too.
