In his latest YouTube video, British bodybuilder and CrossFit athlete Obi Vincent put his cardio fitness and aerobic endurance to the test when he took on a VO2 max workout. The VO2 max gives an indicator of a person’s fitness by measuring their energy output based on the oxygen consumed and carbon dioxide produced during exercise.
“I’ve never tested my fitness,” says Obi. “Throughout school into my twenties, I didn’t do any sports whatsoever. Lazy as anything. I did bodybuilding for years, then CrossFit for two and a half years now, and conditioning. I think if I’d done this two years ago, it would have been a lot worse, trust me. So this is a good lesson. I almost avoided doing any fitness test because I was more scared of what it would look like.”
After 12 minutes (and the equivalent of 3.6 miles) on the assault bike, Obi’s VO2 output is 57
milliliters per minute per kilo. “I should not have done this on the assault bike,” says Obi, breathless from the workout. “That was a bad idea.”
Performance nutritionist Luke points out that the easiest way to up your VO2 max is to lose some weight, which for the stacked Obi would mean losing muscle mass. However, he is already leaner at 242 pounds than he was previously, when he weighed in at 253 pounds, and likes his physique the way it is now, so he’s reluctant to get any smaller.
In addition to highlighting areas of his own personal fitness that he wants to work on, Obi adds that he has learned a lot from Luke in terms of fuelling his body with the right energy sources for workouts. “I’m actually really disappointed with my score… It’ll be interesting to go and start applying some of the things I’ve learned, and see how I get on and do a retest.”
