Does the pelvic floor get the props it deserves? Many fitness professionals who specialize in women’s health think it warrants more respect and attention. Trista Zinn, founder of Hypopressives in Toronto, says the pelvic floor is “overlooked and misunderstood by many.” She adds, “Our quality of life and athletic performance literally rest on [the pelvic floor’s] synergistic ability to function with the core as a whole.”Read More
Some anatomy geeks get a kick out of asking unsuspecting people to name the largest system or external organ in the body. The answer: The integumentary system, of course, which includes the skin, hair, nails, and sebaceous and sweat glands (Springhouse 2002). Its main function is to protect the body from “the outside world” (bacteria, for example), but it also eliminates waste products, regulates body temperature and retains body fluids (AAAS 2017).Read More
No training program is complete without at least some focus on balance, an ability many people take for granted. We monitor the environment and our relationship to gravity quite automatically, thanks to the vestibular system, which helps us maintain our center of mass over a base of support. A properly functioning balance system allows us to see properly while in motion;
helps us orient ourselves to gravity;
determines direction and speed; and
makes automatic postural adjustments (Vestibular Disorders Association).

Talk about workouts! The human tongue stays busy with speaking, tasting and swallowing, not to mention any extra tongue tricks we make it do out of nervous habit (curling, thrusting, etc.). What do you know—or think you know—about this muscular organ?
Do you remember in biology class when your teacher told you the ability to curl your tongue was genetic?
Clients often focus on the many aesthetic benefits of exercise, including weight loss and improved skin tone (Jaret 2011).

Gut microbiota has been a hot topic recently, and for good reason, as it is a key indicator of health. Gut microbiota contains trillions of micro-organisms, including at least 1,000 species of known bacteria, with more than 3 million genes (Gut Microbiota for Health 2016). There are many benefits to having a healthy gut, including but not limited toRead More
When you work with enough clients, eventually you notice all the variations in biomechanics and anatomy. You may or may not remember from your fitness professional certification studies that only about half of people have a psoas minor muscle. When it's there, it lies in front of the psoas major and originates from the sides of the 12th thoracic vertebra (T12), the first lumbar vertebra (L1) and the corresponding intervertebral disk (Farias et al. 2012).Read More
Clients sometimes experience general pain in the knee during or after an exercise session, and while it's not within your scope of practice to diagnose, a broad understanding of issues that affect this important joint can be helpful. Here's a snapshot of plica syndrome.
Plica is a fold of synovial tissue that's a "remnant" of embryologic development. The knee is initially divided into three compartments by membranes, which are then resorbed by the third or fourth month of fetal life (Scuderi et al. 1997).

Here are some popular myths about exercise and pregnancy that you can debunk for clients.Read More
According to the Centers for Disease Control and Prevention, obesity has more than doubled in children and has quadrupled in adolescents over the past 30 years. It now affects 1 in 6 children and adolescents in the United States. This early onset may put children on a life path littered with health troubles. The more educated fitness professionals are about the potential negative outcomes of childhood obesity, the better equipped they are to help.Read More
According to the Physical Activity Council’s 2016 Participation Report, engagement in sports, fitness and related activities increased in 2015, with 56% of the U.S. population aged 6 and older “participating in at least one high caloric burning activity.” While you don’t have to spend a lot of money to start and maintain a fitness program, many people earmark dollars in their personal budgets for products and services that support their fitness goals.Read More
