Thanks for posting this. This looks promising...

I have about 3-3.5 years worth of Apple Health + Fitness data (via my Apple Watch) encompassing daily walks / workouts / runs / HIIT / weight + BMI / etc. I started collecting this religiously during pandemic.

The exported Fitness data is ~3.5GB

I'm looking to do some longitudinal analysis - for my own purposes first, to see how certain indicators have evolved.

Has anyone done something similar? Perhaps in R, Python? Would love to do some tinkering. Any pointers appreciated!

Thanks!!
