0:06 in the primordial soup love the you know
0:09 early early single-celled organisms you
0:12 had glucose being metabolized in the
0:15 absence of oxygen through a 20 step
0:17 process down to a chemical called
0:20 pyruvate and that's kind of how things
0:21 went for a period of time and those
0:24 organisms can only get so big because
0:26 you had to have an energy gradient
0:29 across the cell membrane well as you get
0:32 bigger your volume if you're going to
0:35 double your size your volume increases
0:37 by a factor of eight two times two times
0:40 two is eight but your surface area that
0:43 which creates the energy gradient only
0:49 increases two times to four so if you
0:50 double your size your ability to
0:57 generate energy drops by 50% over time
1:00 other organisms developed that created a
1:02 cell membrane inside of a cell membrane
1:04 that was all folded up on itself so it
1:06 had a lot more surface area to generate
1:10 energy these were little proto bacteria
1:12 and they fed off the waste product of
1:16 these single-celled organisms and they
1:17 can make a lot more energy because they
1:19 had a lot more surface area because of
1:22 everything folded inside this membrane
1:25 inside of a memory well eventually those
1:26 things infected these single-celled
1:29 organisms and had a symbiotic
1:33 relationship those became mitochondria
1:36 so that is the whole relationship
1:38 between the anaerobic component
1:41 metabolism and the Arabic component of
1:46 metabolism so the only way to really
1:48 ramp up the aerobic component of
1:51 metabolism is to deliver substrate more
1:54 quickly to it so the only way to
1:57 stimulate the aerobic sub segment of
2:01 metabolism is by ramping the anaerobic
2:04 portion of metabolism as fast and as
2:08 aggressively as possible so that's why
2:10 we're finding now all these studies on
2:11 high-intensity interval training
2:14 producing equal
2:17 aerobic adaptations in a four-minute
2:19 Tabata protocol as you get from 45
2:22 minutes of steady-state well the same
2:25 thing is true of resistance training and
2:27 what it comes down to is the way that
2:30 you can get at that metabolism and make
2:32 it crank as fast as possible to deliver
2:35 substrate to the mitochondria is by
2:38 doing mechanical work with muscle that's
2:40 the only way you can get at that system
2:43 it only stands to reason that the higher
2:46 the quality of the mechanical work with
2:49 muscle the more you can invoke that
2:52 entire process and resistance training
2:55 just happens to be the mechanism by
2:58 which you can get the highest quality
3:01 mechanical work with muscle to drive
3:05 this whole process now if we take you
3:08 know Kim Cooper aerobic from Kenneth
3:11 Cooper's aerobics from the 1970s that
3:14 said what happens in the mitochondria is
3:16 somehow linked directly to the heart and
3:19 the vasculature that makes no sense
3:21 physiologically at all the heart and
3:23 blood vessels service the entire
3:26 functioning of metabolism the entire
3:30 cell not a sub-segment of the cell so it
3:33 turns out that the best cardiovascular
3:36 training you can do is the type of
3:39 training that invokes the totality of
3:41 metabolism to the most aggressive degree
3:44 possible and that just so happens to be
3:47 properly performed resistance training
