Most fitness professionals believe they are giving members accurate, up-to-date guidance. The research says otherwise.
Episode 18 of The Research Debrief examines two papers that reveal a significant disconnect between what the science says about resistance training and what practitioners and exercisers actually believe — and makes the case for why an evidence-based approach is essential for the fitness industry’s credibility and long-term impact.

What This Episode Covers
This episode steps back from individual studies to examine a foundational question: why does evidence-based practice matter and what happens when the. fitness industry operates without it? Drawing on two recent papers, Luke Carlson and Rachel Chonko explore the gap between scientific research and real-world gym practice, and what it costs the industry when that gap goes unaddressed.
Key discussion points include:
- A paper published in Physical Education and Sports Studies and Research, which reviewed the literature on resistance training and found a widespread lack of scientific awareness among practitioners and exercisers alike — including the persistence of myths such as the belief that resistance training reduces flexibility and that plant-based proteins are inferior for muscle hypertrophy.
- A study published in Scientific Reports, which presented regular gym-goers with statement categorized as either myth or scientifically supported fact. Participants could correctly identify which was only 50% of the time. The same pattern held for exercise professionals, including physiotherapists and fitness educators worldwide.
- What “evidence-based” actually means in practice: not complexity or jargon, but a commitment to consulting the research and combining those findings with professional experience and individual client preferences.
- Why passion and personal experience, while valuable, are not a substitute for an evidence-based approach and how the industry’s reliance on enthusiasm over expertise has contributed to the credibility gap the research describes.
Why This Matters for Operators
The consumer entering a health club today is more informed than ever. They are listening to podcasts, using AI to research their workouts and driving with questions that require more than enthusiasm to answer. When the research shows that gym-goers and fitness professionals alike struggle to tell myth from fact, it signals an industry-wide credibility problem and an opportunity for operators willing to close that gap.
Key implications include:
- Expertise, not passion, is what builds long-term trust with consumers.
- Building a brand around evidence-based practice is a concrete differentiator.
- Staff education programs that incorporate actual engagement with current science directly raise the quality of every member interaction and reduce the likelihood that outdated myths are being passed along the fitness floor.
