The internet is a wellspring of knowledge. The vast majority with access to it turn to Google and social media for answers to any questions they may have about anything. That is typically the case for those seeking health, fitness, and bodybuilding information as well. However, much of the information available online is rooted in personal opinion and lacks scientific evidence. This can pose a considerable risk, particularly for individuals with specific health conditions.
On the Oct. 27, 2023, episode of The Mike O’Hearn Show, the show’s namesake sat with Dr. Gabrielle Lyon, a functional medicine physician and author of “Forever Strong,” to bust myths surrounding fitness and training. Check it out the video below, courtesy of Generation Iron’s YouTube channel:
Dr. Lyon holds a fellowship in nutritional sciences and geriatrics. The social media boom started around the time she began her clinical practice. The misinformation in the fitness space took her aback. “It definitely wasn’t going to make anyone stronger, and it was a whole bunch of BS,” said Dr. Lyon. She began posting on social media to debunk the falsehoods and misconceptions within the health and fitness industry.
“We can change the trajectory of how we age,” said Dr. Lyon. The threat of misinformation about aging on social media is that it so easily spreads. Misinformation can be repeated so often that people believe it. There’s a prevalent fitness dogma that letting young children lift weights can stall their growth. Dr. Lyon clarified that there isn’t sufficient scientific support to back up that claim. Children can exercise as soon as they are curious about it. (1)
According to a Clinical Journal of Sport Medicine study, “training protocols with weights and resistance machines and with supervision…are relatively safe and do not negatively impact growth and maturation of pre- and early-pubertal youth.” (2)
Dr. Lyon highlighted another common misconception about women lifting weights and how it can lead to a more masculine appearance. Masculinity is subjective, so how to measure it isn’t clear. Furthermore, most female gym goers don’t necessarily build the same amount of muscle tissue as their male counterparts due to variations in natural testosterone production. (3)
“Go into any gym, and it’s mostly the guys in the free weights area. Women are doing cardio because they have all these myths,” said Dr. Lyon. “These myths stem out of discomfort and not a real belief.”
Dr. Lyon opined that most women don’t actually believe they’ll get bulky lifting weights but rather want to avoid the time and effort strength training entails and use the fear of a more masculine appearance as an excuse to avoid lifting weights.
O’Hearn quipped that most male gym goers struggle to build muscle — a combination of sufficient intensity and frequency while following a diet that provides enough calories and protein are the common building blocks to add muscle tissue. In Laymen’s terms, it’s not easy to add muscle mass, so O’Hearn feels female gym goers shouldn’t worry about this made-up threat of looking masculine as a result of resistance training.
Many female gym goers might perform various triceps exercises hoping to get rid of underarm fat, popularly known as “bat wings.” However, spot reduction through weight training is a myth. A Medicine & Science in Sports & Exercise study concluded that “Subcutaneous fat changes resulting from resistance training varied by gender…MRI found a generalized subcutaneous fat loss independent of gender, supporting the notion that spot reduction does not occur as a result of resistance training.” (4)
When scrolling through Instagram or reading about health and fitness online without peer-reviewed research supporting the claims made, or believing fitness influencers at their word, take everything with a grain of salt.
