Hack Speed & Conserve Energy by Killing Stance by Mark Hatmaker

Before we get into the scientific nitty-gritty, let’s do a little self-experimentation.

I want you to stand up right now and hit ten rapid Hindu Squats [deep-knee bends for the non-grappling minded.]

Did you do it? Ten hard and fast?

Now, let’s self-assess. How do the legs feel?

There is a possibility that the lungs required you to puff a wee bit and the heartrate elevated, but I wager that the low repetition number has not made any fatiguing demands on your legs. They are probably good to go for another ten.

Since the effects we are feeling are not leg fatigue but maybe elevated heart-rate and respiration let’s hit ten more but…

This time I want you to time them in the following manner.

·        Rather than ten hard and fast, let’s go leisurely, drop down for Squat 1 and stay there for one solid minute, then return to standing.

·        That’s rep one. Continue on down the line for a total of ten.

I wager the majority who submit to the self-experiment will do the first hard fast squats no problem but will become a bit bored by the next slow ten but…the bodily sensations accrued by the ten will really pave the way for today’s lesson.

Now, whether you did the self-experiment or not, here’s the upshot. The hard fast ten squats will feel noticeably less taxing than the slow ten.

Now why should this be?

After all, in the slow ten we are essentially in a resting position—the deep squat aka 3rd-world squat.

The difference in effort is not one of mere perception it is one of bio-mechanical function.

When we squat with speed the extensor muscles, although no longer required to remain standing, remain under tension all the same to control the rate of descent.

In the fast iterations of the squat where an immediate turnaround is required [rising back to standing] the extensors still under load [or use-utility] are able to increase the present tension and make the rapid rise easily.

In the slower iterations we stop at the bottom and the extensors which were under-tension or load during descent disengage—the tension decays.

To return to standing, we must place them back under load walking the scale back up from 0% use to full use.

Fast iterations of the squat allow the leg musculature to utilize “elastic-loading” where your extensors behave as rubber bands stretched and tensed for use.

Slow iterations are slack rubber-bands that require full musculature engagement with zero elastic aid.

Elastic recoil aids speed and conserves energy. When we run our calf muscles and Achilles tendons do not go to zero-slack as the foot peels off the ground with each stride—there is still a tension loaded in the toes, foot, Achilles tendons, and calf muscles that allow for elastic rebound once the next foot stride is placed.

Experiment #2

Sprint 50 yards as hard and fast as you can.

At the conclusion note your internal state. I wager just as with fast squats you will have elevated respiration and heart rate but 50 yards at speed will not be experienced as leg taxing.

Now, cover that same 50 yards but this time take one bounding step and land on a foot—pause for 3-seconds, bound to the next, and so on until the distance is covered.

Important: When making these bounding steps land with a flexed knee, remain in knee flex which one would assume would aid the bounding task, but the 3-second pause allows for elastic decay.

After this is complete, again note internal states. Elevated respiration and heart-rate and…a remarkable increase in perceived leg exertion as compared with the sprint.

Let’s bring this to combat [hell, and all athletic endeavor].

·        Any use of stances that advises starting from stock-still by bio-mechanical definition cannot utilize elastic loading for speed or energy-conservation.

·        Any footwork of the slow-plodding variety will not utilize elastic load, or at the very least small elastic load assistance.

Static stances and/or slow deliberate footwork is by mechanical definition slower and ultimately more taxing.

I am not advocating, bouncing bounding footwork where the athlete is barely in contact with the ground. That is always unwise. Such “over-activity” can lead to inefficient energy-expenditure via anaerobic pathway and the reduced contact with the ground makes weight transfers and direction changes less efficient.

What we may wisely decide is to find the method of movement that remains cognizant of elastic load to better our speed and reduce relative fatigue.

Warrior Awareness Drills by Mark Hatmaker

THE Primary Factor in self-protection/self-defense is situational awareness. Keeping in mind that crime is, more often than not, a product of opportunity, if we take steps to reduce opportunity to as close to nil as we can manage we have gone a long way to rendering our physical tactical training needless [that’s a good thing.]
Yes, having defensive tactical skills in the back-pocket is a great ace to carry day-to-day but all the more useful to saving your life or the lives of loved ones is a honed awareness, a ready alertness to what is occurring around you every single day.
Here’s the problem, maintaining such awareness is a Tough job with a capital T as most of our daily lives are safe and mundane [also a good thing] and this very safety allows us to backslide in good awareness practices. Without daily danger-stressors we easily fall into default comfort mode.
A useful practice to return awareness/alertness to the fore is to gamify your awareness, that is, to use a series of specific…

Apache Running by Mark Hatmaker

Of the many Native American tribes of the southwest United States and Mexico the various bands of Apache carry a reputation for fierceness, resourcefulness, and an almost superhuman stamina. The name “Apache” is perhaps a misnomer as it refers to several different tribes that are loosely and collectively referred to as Apache, which is actually a variant of a Zuni word Apachu that this pueblo tribe applied to the collective bands. Apachu in Zuni translates roughly to “enemy” which is a telling detail that shines a light on the warrior nature of these collective tribes.
Among the various Apache tribes you will find the Kiowa, Mescalero, Jicarilla, Chiricahua (or “Cherry-Cows” as early Texas settlers called them), and the Lipan. These bands sustained themselves by conducting raids on the various settled pueblo tribes, Mexican villages, and the encroaching American settlers. These American settlers were often immigrants of all nationalities with a strong contingent of German, Polish, and …

Awareness Drill: The Top-Down Scan by Mark Hatmaker

American Indians, scouts, and indigenous trackers the world over have been observed to survey terrain/territory in the following manner.
A scan of the sky overhead, then towards the horizon, and then finally moving slowly towards the ground.
The reason being that outdoors, what is overhead-the clouds, flying birds, monkeys in trees, the perched jaguar—these overhead conditions change more rapidly than what is at ground level.
It has been observed by sociologists that Western man whether on a hike outdoors or in an urban environment seldom looks up from the ground or above eye-level. [I would wager that today, he seldom looks up from his phone.]
For the next week I suggest, whether indoors or out, we adopt this native tracker habit. As you step into each new environment [or familiar ones for that matter] scan from the top down.
I find that this grounds me in the awareness mindset. For example, I step into my local Wal-Mart [or an unfamiliar box store while travelling] starting at the top, t…
