The Norwegian 4x4 high intensity interval workout is the gold standard for improving your VO2 Max according to Rhonda Patrick and many longevity experts. You need to hit 85%-95% of your max heart rate for 4 minutes followed by 3 minutes recovery. I do a 6-week test of the brutal workout at home on assault bike, rower, treadmill and ski erg followed by a VO2 Max test to see how I improved my maximum oxygen uptake. Does it work? I'll also show you what it does to my blood sugar. VO2 max test was taken at @LATriFit Thanks to @tricoachmo! Want to get better at life with me?
