“It is well known the body responds to exercise by developing NEW capillaries within the muscle.” A study done as early as 1946 show it’s possible to increase new capillaries by as much as 45%.
D. Barker reported in the quarterly journal of Micro Science that a single neuron cannot activate more than the total number of muscle fibers it innervates. Furthermore, it often doesn’t even activate all it’s assigned muscle fibers. But if the stimulus is strong enough and frequent enough, the neurons are capable of a tremendously powerful “domino effect stimulation.”

Here’s what happens...

A nerve impulse travels from the brain to the central nervous system and out to the nerve cells like a spark traveling along a string of gunpowder at almost 270 miles per hour. If this burst of power is of sufficient strength it will not only trigger all it’s assigned muscle fibers, but it will arc to adjacent neurons as well.
The junction or “arcing” between two nerve fibers is called a synapse. Here the ends of the axons are in very close contact with the brush like endings of the dendrites of other neurons... the synapse becomes the point of communication between one neuron and another. The nervous impulse travels along an axon and across the synapse to the dendrites of another neuron.
If the impulse is powerful enough it will arc over those with high resistance as well. (Kinesiology and Applied Anatomy, Rasch and Burke)
What does all this mean to us? Let me rephrase what Rasch and Burke are saying. Ever get a cramp in your calf muscle in the middle of the night. Ever noticed how hard it is? That, my friend, is a total Synapse.
Once you gain sufficient control of your Neuro-Muscular system where you command not only the power of the nervous impulse but also the rep rate of the “impulse volley” you’ll make progress you never thought possible. But first you need to become friends with your nervous system because it’s the nerves that flex the muscle and...

“If You Can’t Flex It You Can’t Build It”

Just so you’ll know what I’m talking about, pick any particular muscle on your body and see how hard you can flex it. Then, when you’re giving it your all, feel the muscle and see if it’s still a little spongy and soft.
Now... pick an area on your body... you’d like to be hard as a rock like your midsection... or your thigh. Is it softer still?
You can see why you’re hiding flab in that very spot. If you can’t even make the muscle hard, how do you expect to get rid of the fat smothering the muscle underneath.
I know... they tell us there’s no such thing as spot reducing but... believe me when you learn to flex those abs, intercostals, spinal erectors or whatever as hard as a rock... Those muscles will go on a witch hunt for energy that will rival the Salem Witch hunts of the 1800’s.
Then again, you don’t have to do it this way. You can do endless hours of aerobics and examine every gram of food for fat but... wouldn’t you rather use a method that works not just when you’re training but... 24 hours a day.
Much of the secret is hidden in the Power Of The Synapse. Pick the very muscle you just finished working. Close your eyes and... try to flex the muscle harder than you have ever flexed it before in your life.
When you focus... everything you’ve got... on flexing the muscle and continue sending this impulse volley to the muscle, a strange thing happens. The repeated volleys of nervous impulses eventually cause a maximum response.In other words when you “crank up the voltage” to one particular muscle group and keep sending flex signals... gradually that muscle flexes to it’s maximum. If this is difficult at first, don’t get discouraged. I couldn’t even flex, let alone get a synapse on my stomach muscles. You’ll get better quickly and while you’re learning, you’ll be burning fat at an accelerated rate. Because now you’re not only getting more muscle fibers coming to life... you’re building new muscle fibers as well. One day you’ll achieve a Total Synapse as the muscle flexes so hard it hits home like a knife sliding into a scabbard. When that happens you’re on your way to the hardest most muscular body you’ve ever had in your life and you’ll only be spending 9 minutes a day to do it.
