I've never seen one of these that could handle accommodating resistance (bands and chains) or partial range of motion. This would I think have then be different movements, same as using Strong on iOS.
I use the metadata to capture partial ranges and accommodating resistance. For example
Bench:
# grip: index on smooth
# pin height: 16 inches off bench
# chains: 100lbs
135 5r
225 3r
...
And on and on. I have added pieces to the language over the two years I’ve been using it and I hope to write a better guide (maybe short book) on how you can capture different kinds of training.Thanks for looking!
