Johnson’s many techniques have been built up into something that he calls his ‘Blueprint Protocol’, and the whole system is hugely expensive, costing an estimated $2 million each year. Trackers are, in fact, very much key to all of his aims – Johnson is constantly monitoring a whole host of health metrics, some of them simple like his bench press averages, and others completely bizarre, like his website’s boast about his “night-time erections, 179 min, better than average 18 year old”. The list of ‘routine measurements’ that Johnson undergoes according to his website includes things like weight, body fat, muscle mass, body water, BMI, blood glucose, and regular MRI scans and ultrasounds to screen for any issues. The jury is very much out on whether Johnson’s approach is actually successful – social media seems divided on whether he does indeed look far younger than his 46 years, or if the hyper-fixation on age has left him looking a certain way to make a specific number irrelevant.
