So I do that very thing with it! I train Westside style lately coming back to it after 15 years.
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!
