I am on Bystolic, an older Beta blocker. In my experience it is limiting the gains I can make on TR. My FTP is stuck at about 2.6 to 2.8 W/kg. At 57 I am not complaining. I am still one of the faster guys on the group ride. I am tending to go for riding that’s not so intense. Long days at fast pace. Not everyone can go forever at sweet spot. I can and the Beta blocker isn’t an issue.
