0:00.0 | My name is Ben Greenfield and on this episode of the Boundless Life podcast, |
0:04.8 | your cardiovascular fitness is split into four different categories. |
0:07.4 | Your fat burning capacity, your VO2 max, your mitochondrial density, |
0:10.8 | and your ability to be able to tolerate lactic acid, aka the burn. |
0:14.7 | If you are just walking or just sprinting, you're not going to hit all those variables. |
0:19.4 | For V02 max, once every one to two |
0:21.4 | weeks, you do a hard, maximum sustainable pace effort, like a four by four minutes on a bike |
0:26.9 | with four minutes of recovery after each. Perlactic acid tolerance, you go hard and then you recover, |
0:32.5 | but not for very long. This would be like the classic Tabata set. 20 seconds hard, 10 seconds easy, |

1:01.8 | Cardio is technically four different things. |
1:03.1 | So if you hit those four, if you two max mitochondrial density, lactate tolerance, and fat-burning |
1:07.3 | capacity, and those are kind of like woven throughout your week, then you're going to get all of them. |
1:12.7 | Welcome to The Boundless Life with me, your host, Ben Greenfield. |
