In this “Master Instructor Roundtable,” co-hosts, and NASM Master Instructors, Wendy Batts, and Marty Miller, take a deep dive into some of the most persistent myths in strength training. Whether you’re a fitness newbie, a seasoned trainer, or just fascinated by health science, this lively discussion will help clear up common misconceptions that still linger in gyms everywhere.

The two tackle myths like the idea that lifting heavy weights automatically leads to bulkiness, especially for women, and whether kids and seniors should steer clear of strength training. They dispel the old “high reps for toning, low reps for bulk” rule, explain why “muscle confusion” isn’t the magic bullet it’s made out to be, and set the record straight on spot fat reduction and the safety of squats for your knees.

Drawing on up-to-date research, years of professional experience, and practical examples (from training young athletes to keeping grandparents strong and independent), the hosts break down how strength training impacts everyone—at every age. They cover how adaptations really work, the crucial role nutrition plays in muscle growth, and why proper technique and progression always trump trendy workout fads.

With plenty of humor, relatable anecdotes, and actionable advice, Wendy and Marty equip both trainers and clients with the facts they need to make smarter choices in and out of the gym. If you want to gain confidence in your training—or help others do the same—don’t miss this myth-busting episode that promises to educate and empower.
