00:00

you could be building muscle almost

00:01

twice as fast as you are right now now

00:04

with this what would stretch focus

00:05

training which is seemed to crack the

00:07

code to build the muscle I've even

00:09

started experimenting it with my own

00:10

training and honestly it seems like it's

00:12

working don't just take my word for it

00:14

though I've assembled my Elite crew of

00:16

researchers to dive into the science

00:18

separate the truth from bad and figure

00:21

out the best way to use this training to

00:23

build muscle faster so whenever you lift

00:25

weights your muscles contract to lift

00:27

the weight up and then stretch in order

00:29

to lower the weight back down but

00:31

something special seems to happen when

00:33

your muscles become stretched under load

00:35

the muscles can sense the stretch in the

00:37

contractile units and in response kick

00:40

start a complex process that tells the

00:42

body to build more muscle this is what

00:45

researchers now term stretch mediated

00:48

hypertrophy but not until fairly

00:50

recently has more specific research

00:52

actually put this Theory to the test and

00:55

the findings were quite surprising even

00:57

to me there's four studies I want to

00:59

look at with each of them testing a

01:01

different muscle group the first two

01:03

tested what would happen if you only

01:05

perform the bottom part of an exercise

01:07

where the muscle is stretched one of the

01:09

two published just last year tested this

01:12

using preacher curls and assessed the

01:14

growth in the biceps after five weeks

01:16

the result the subjects that performed

01:19

only the bottom half of the curl

01:20

experienced 2.6 times more biceps growth

01:24

than those who only perform the top half

01:26

of the curl pretty cool right another

01:29

study also published just last year

01:30

replicated an almost identical design

01:33

but this time on the leg muscles using

01:35

leg extensions they had subjects perform

01:38

the bottom versus top half of the leg

01:40

extensions and one more group who did

01:42

the full range of motion they measured

01:44

the growth of the Quad muscles at four

01:46

different sites after 12 weeks growth at
