Bryan Johnson tests his VO2 max, leg press single-rep max, and bench press single-rep max to track whether his body is aging or improving. He plots the results on a personal age graph to see his progress over time and stay motivated in his training.
Okay. We're here at the gym. We're going to do our annual fitness testing. We're going to do single rep, max leg press, bench press, and VO2 max. These days are always really exciting because I train all the time and I don't know, checking in for this intermittent progress is really encouraging. It keeps me motivated on a daily basis because I know I'm going to come, I'm going to look at my score and I'm going to look at the age graph and I'm going to say, am I aging or am I maintaining neutral or am I getting better? So these are really exciting days.
