Chilton Hawk: Exercising During A Pandemic With KAATSU

For who? Blue collar employees, white collar employees, stay-at-home employees, students
For what? Fitness, wellness, strength, functional movement, mobility, flexibility, balance

Chilton Hawk is an Assistant Laboratory Animal Technician at the University of Utah. He wrote a review (Exercising during a Pandemic) of the KAATSU Cycle 2.0 for his fellow employees of the Mountain West branch of the American Association for Laboratory Animal Science (AALAS).

The AALAS is a membership association of professionals employed around the world in academia, government, and private industry who are dedicated to the humane care and treatment of laboratory animals, as well as the quality research that leads to scientific gains that benefit people and animals.

Exercising during a Pandemic - A Review Submitted by Chilton Hawk

For many folks, trying to get good quality exercise has been challenging in the current pandemic. People who like to use gyms have found that many of them are closed. Gyms do have a variety of equipment that most of us cannot afford nor have space for at home. Doing exercise outside is generally weather dependent. One possible solution is blood flow resistance (BFR) exercises. It is effective at building muscle mass and improving blood circulation in a short amount of time.

Back in the 60s, Yoshiaki Sato was sitting on the floor in Buddha style. When he tried to get up, he experienced severe cramping in his leg. This is an experience that most of us have had at one time or another. As he rubbed his leg, he was wondering how to improve the blood flow. One of the problems that humans have with circulation is the heart pumps blood out, but the blood to return to the heart is working against gravity. Sato spent years of research trying to figure out a solution.

The result of his research was the development of blood flow resistance (BFR) exercises and equipment. He created stretchable, narrow pneumatic armbands KAATSU and leg bands that inflate like blood pressure cuffs. The arm bands are placed just below the deltoid muscle and above the biceps. The leg bands are placed as close to the groin as possible. The bands automatically and repeatedly inflate and deflate in 8 steps. Each step increases slightly in pressure.

This compression and decompression help push the blood to the distal ends of the limbs while the venous blood slows its return to the torso and pools in the limb. During the exercise session, skin color changes to a pinkish or reddish color. This indicates improved circulation and increased vascular tissue elasticity while serving as the catalyst for hormone production. Blood circulation is important to deliver nutrients to the cells and remove the toxins.

There are some videos on YouTube that give some idea of how to safely and properly use the BFR equipment. From personal experience, I would recommend the Dr. Cory KAATSU series (see below*). The exercise program is fairly simple. It is important to start with the armbands allowing the circulatory system to warm up for the next round of exercises. The reason I brought the KAATSU was for neuropathy. My neuropathy is caused by reduced blood flow to the legs and feet that create mobility and balance issues. It surprised me that the therapy results were immediately noticeable. I felt greater mobility, speed, and balance, and also noticed much better sleep at night, which allows greater cognitive ability. An added benefit is that I am building muscle mass with very few exercises.

KAATSU can be performed in a small area, with or without any special exercise equipment. This convenience and portability enable exercise or rehabilitation to be done anywhere anytime.

Today millions of people worldwide are enjoying the benefits of KAATSU which include quick recovery from injuries, building lean muscle, increased production of nitric acid for improved cardiovascular health, improved metabolism, increased energy, and endurance, according to the KAATSU website. Other benefits will be made known as further research is done.

The product being reviewed here is the KAATSU Cycle 2.0 which includes the control unit (that adjusts the pressure and timing of the compression and decompression) a pair of armbands and a pair of leg bands. The bands come in small, medium, large, and extra-large. Instructions for choosing the right size are on the website at Kaatsu.com. The price of the unit is $899.95 with a one-year warranty. Customer service is excellent. I have sent several emails with questions and the company answered in a very timely manner

KAATSU Isometrics: Benefits In Strength, Speed, Stamina

For who? Work-at-home employees, student-athletes, competitive athletes
For what? Speed, strength, stamina, isometric exercises



One of the most surprising places to realize the benefits of KAATSU is an economy-class seat in an airplane.

Similarly, the benefits of KAATSU the original BFR can be realized while you are sitting down to watch a movie.

In both cases, you can do isometric exercises by repeatedly pushing your arms against an immobile armrest or placing the palms of your hands and pushg against one other. These isometric exercises engage your muscles without movement and nearly eliminate any wear and tear on your joints.

There are many kinds of isometric exercises that you can do with KAATSU Air Bands on either your arms or your legs:

* sit down and extend your legs out and hold while contracting your muscle
* wall squats
* do a heel raise and hold
* stand up and lift one leg and hold
* do biceps curls and hold while contracting your muscle
* do triceps extension and hold while contracting your muscle
* grasping your hands together and pulling apart
* hold yoga poses
* planks
* chest press against a wall
* holding a push-up position
* lying down with your legs straight and your arms at your side while holding your head off the ground

Isometrics engages more muscle fibers than the movements with normal movement - and like KAATSU, can be done anywhere anytime while pushing or pulling against an immobile object or another body part. KAATSU augments the benefits while presenting fewer risks than traditional exercises with movement.

You can also work on a muscle from different angles and with different pressures or different degrees of tension. During isotonic and isokinetic movements, peak tension is only reached during a very small portion of the movement. But by holding a specific position under maximum tension, especially with KAATSU Air Bands on, the tension - and benefits - increase.

Additionally, and contrary to common thinking, isometrics can recruit the most fast-twitch muscle fibers during training. That is, you can get faster by not moving if your time under tension is maximized.

Additionally, isometric exercises can be effective at improving your cardiovascular fitness. During isometric exercises, the capillaries and veins (which hold 70% of your total blood volume in your body) are squeezed by the muscle fibers. This temporary and moderate stress forces your body to adapt and it responds by building more blood vessels and improving the elasticity in your blood vessels.

If you are waiting in a car and have your KAATSU equipment with you, throw on your KAATSU Air Bands on your arms or legs, and do some creative isometric exercises while just sitting. Build strength, speed and stamina with KAATSU isometrics.
