I don’t do gym equipment training. I believe the “weight workout” is designed to emulate the strain from that. IOW something that trashes your legs the next day, enough that you’d want it on your Planner to push form to yellow for a time.
I do bodyweight, resistance bands, and kettle bell workouts, irregularly. Not enough to affect me the next day.
You can open the “weight workout” in Workout Designer, select Copy button, then edit and save changes. For example, to lower the strain score increase MMP incrementally (.7 to .9 or 1.0).
If you do enough strain work outside of cycling and want to include it, you can add the activity manually with estimated XSS. Easy endurance for an hour would be in the 45 XSS range.
