You missed my point. It does, but it doesn't change fitness.
Nor is it really cycling related. If I did gym work and was a triathlete or duathlete then i'd add it. But being a cyclist only, i feel it's better to exclude it from the chart, as it's hard to quantify in TSS figure and just make a note.

No, you missed my point.

What is fitness? If weights session does change TSS and ATL why aren't you changing them?

If you did a gym session and raced the day after you really think that gym time doesn't affect your legs just because it wasn't on a bike?
