Going Primal

Going Primal

We like to do primal crawls because it develops what is called reflexive strength. These CBFers beautifully demonstrate reflexive strength in action.

Note in the video how everyone is able to reach out and support themselves with arms and hands because strong rotator cuffs hold the upper arm bone firmly in place while bearing the full weight of the body. Ditto in the hips where a stable platform is provided for the large muscles in the legs to propel you forwards.

Strong cores ensure straight backs as limbs move on opposite sides (contra laterally) – you don’t see exaggerated twisting or sagging in the spine.

Because crawling is a total body exercise – arms, legs, core, feet, neck – there’s a tremendous amount of activity going on in the central nervous system to time and sequence every movement.

All of this makes for a physically skilled older adult who can safely fall or push a car stuck in the snow or hold onto a leashed dog that takes off after a squirrel. And walk or run.

 

 

 

 

 

 

Grappling with the Exercise Grizzly

Grappling with the Exercise Grizzly 

Your body reacts to exercise the same way it reacts to an encounter with a grizzly bear – it triggers the fight-or-flight response.

Because exercise is a major stressor, your body releases a cascade of hormones to ensure you can physically perform to meet the challenge, just as if you were in a life threatening situation.

Just consider what epinephrine, a hormone secreted by your adrenal glands, does for you as your exercise intensifies and you start to feel discomfort:

- strengthens your heart contractions

- expands arteries (vasodilation) supplying blood to your heart and muscles

- constricts (vasoconstriction) blood supply in non-exercising muscles to force blood to muscles in use

- widens passages in the lungs to maximize oxygen intake

- reduces digestive activity to divert blood to exercising muscles

- mobilizes stored carbohydrates and fats to provide energy (which is why exercise helps sustain weight loss)

- increases alertness (but there’s a tradeoff – you have faster reaction times, but will find it hard to do math – try to do multiplication tables while on the ropes).

Exercise in the gym is preparation for real life in more ways than we realize. You’re developing will power, strength, endurance, and resilience as you grapple with that grizzly in the gym.
