Bryan Johnson's one-hour daily workout combines weight training, cardio, and flexibility, but he's not chasing marathon times. He tracks roughly a hundred physiological markers—VO₂ max, muscle ultrasound, whole-body MRI—all aimed at one goal: lowering cellular entropy to reverse aging.
What has the data said to you about the optimal setup for a training protocol for yourself? Yeah, I work out an hour a day so basically I try to flex and stretch every muscle of my body and we've worked back through the science of cardio zones to be in and we also look at this in terms of measurements of my VO2 max of my flexibility of my tendon ligament strength of my we measure my muscle with ultrasound. We do whole body fat on mri. We're using these COR quantitative endpoints. We probably do a hundred different markers that quantifies my exercise protocol and they're all markers that we can map to goal alignment. Problem I'm working on is my 35 trillion cells having less entropy. So I'm not trying to engage in a marathon. I'm not trying to achieve some athletic record and so really it's just that one goal and so yeah so it's just a bunch of weights. Cardio flexibility, strength training.
