On high-intensity exercise days, Bryan Johnson uses a bike, elliptical, or rowing machine for warm-up and interval training, aiming for heart rates of 130-140 bpm.

“+ 30 min cardio”

“On high intensity exercise days one of three possibilities I've got a bike ectal and a roll machine so typically I'll do 5 or 10 minutes on the bike warm up get my heart rate in like the 130s 140s and and then I'll do the elliptic hoal I'll do some some uh pulse training some high intensity intervals and then uh other days I'll warm up with the row machine and then jump to the elliptical for the high-intensity intervals for v2 Max training”

“and I'll use a polar strap to do ECG to get an accurate heart rate and I'll maintain around 130 140 range”

“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 quantitative endpoints”
