Increasing Zone 2 training from 1 hour to 1.5 hours, four days a week, led to an additional 10-pound weight loss, totaling approximately 50 pounds lost.

“I lost 33 pounds and I stopped there. I could not lose more than that. I needed to then increase my dose. So I went from one hour to an hour and a half, four days a week. I lost another 10 pounds. So I lost a total of around 50 pounds, 47 to 50 pounds.”
