It’s time to revisit one of the basics of biology: mitochondria. These organelles, which occur in almost all types of human cells, generate adenosine triphosphate (ATP), the energy that cells use (Newman 2017; Newman 2018). They are critical for powering metabolic processes, making them a building block of physical health and fitness.Read More
Andrew Sung had tried multiple training programs, but nothing seemed to help him reach his fitness goals. When he found personal trainer and competitive bodybuilder Aaron Seaton, that all changed.
“Andrew came to me with a defeated outlook,” says Seaton, a multicertified NASM trainer. Still, “he was highly motivated; just unsure how to put the pieces together.”Read More
As the control center for the body’s nervous system, the brain participates in every human function. From sensing to controlling motor skills, its vital role in movement means this cognitive powerhouse is—literally—the brains behind your work as a fitness professional.
There are three main components that make up your mind:Read More
As a fit pro, you are all too familiar with training muscles to build strength, mass and better movement in your clients—by now, you might consider it muscle memory!
Yet, as a major system present throughout the body, the muscular system is vast and intricate with plenty to explore. After all, muscles produce every movement, from the basic, like digestion and respiration, to the complex, like running, dancing and weightlifting.Read More
Many of your clients likely work desk jobs and sit most of the day. This is not an ideal situation for many reasons, one being the risk of developing chronic lower-back pain. If you or a client is experiencing aches or sharp pains in the lower back, the issue may stem from problems with the quadratus lumborum.Read More
Every time you take a step, your piriformis muscles help to keep your stride in good form.
The piriformis is a flat, pyramid-shaped muscle in the gluteal region (you have one on each side of the body). Located behind the gluteus maximus, the piriformis attaches to the base of the spine (the sacrum) on one end and to the top of the femur, the trochanter, on the other end (Kenhub 2019; Chang, Jeno & Varacallo 2019).Read More
How much do you know about your scalene muscles? If you just tilted your head in confusion, you can attribute that simple movement, in part, to your scalenes, three pairs of muscular tissue that flank the sides of the neck.
Anterior scalenes, on the front side of the neck, connect the third through sixth cervical vertebrae to the first rib.Read More
We do this every moment of the day; it can help us relax, and it speeds up when we exert ourselves—all without so much as a thought. Inhale. Exhale. Breathe! This important gas exchange, which keeps us alive, can only happen thanks to the miraculous work of the lungs.Read More
The hypothalamus occupies little real estate in the brain, but it houses nuclei critical to many of the body’s regulatory functions. Situated just beneath the thalamus, it keeps the body in homeostasis by controlling the sleep-wake cycle, body temperature, hunger and thirst, sex drive, fluid balance, emotions, blood pressure, and heart rate (Johnson 2018).Read More
