For these ME workouts you gage preparedness or recovery state on how your legs feel. Are they tired when climbing the stairs? Then you are not recovered. Another way to know with the ME workouts is that you should see significant improvement from week to week. If you don’t see that then you are 99% of the time not recovered. TSS and TSB are good metrics but you must consider how you feel and not blindly adhere to the numbers regardless of fatigue.
