Hi all, I have the same problem here, “very tired” for a couple of days after workouts. Most times I saw the red stars, one time yellow, but I still doing workouts (cycling two times a week to work an back (75km both rides) and have a ride at the weekend (70-80 km) without being very tired a few days. Last Weekly Stats XXS/day and TL: 76.3 / 45.3 ; 91.5 / 50.4 ; 70.1 / 51.9. But I don’t have a mind how to get values to have Xert for a right sight on my fitness. There are no other sports or heavy work I did. Maybe one think is, that Xert “What’s My FTP” says 234 Watts a few days ago, but my Fitness Signature says TP 223 Watts, so that my workouts calculated much harder than I really do? I cycle 2300km last year, 2800 this year. Maybe this level is too low for Xert calculation? Any suggestions?
