In his newest YouTube video, British bodybuilder and CrossFit athlete Obi Vincent put his cardio health and cardio endurance to the check when he took on a VO2 max exercise. The VO2 max provides an indicator of an individual’s health by measuring their power output based mostly on the oxygen consumed and carbon dioxide produced throughout train.

“I’ve by no means examined my health,” says Obi. “All through faculty into my twenties, I did not do any sports activities in anyway. Lazy as something. I did bodybuilding for years, then CrossFit for 2 and a half years now, and conditioning. I believe if I might completed this two years in the past, it could have been so much worse, belief me. So this can be a good lesson. I nearly prevented doing any health check as a result of I used to be extra terrified of what it could seem like.”

After 12 minutes (and the equal of three.6 miles) on the assault bike, Obi’s VO2 output is 57 millileters per minute per kilo. “I shouldn’t have completed this on the assault bike,” says Obi, breathless from the exercise. “That was a foul thought.”
