Over 70 and Shredded: The Guide to Building Muscle at Any Age | Michelle & Joan MacDonald

About this video

Dr. Lyon interviews fitness coaches Michelle Macdonald and her mother Joan (nearly 80, who began training at 71) about strength training for women over 40. They discuss the importance of resistance training regardless of age, Michelle’s journey through severe eating disorders, practical training advice for beginners, and challenging narratives around women, aging, and muscle building. The conversation emphasizes consistency, proper coaching, nervous system regulation, and reframing strength training as essential for long-term health and independence.

Key takeaways

• Michelle argues there is no statistical difference in muscle-building rates between men and women, even through menopause, though it may take longer for older adults
• The speakers emphasize consistency and proper coaching as the most critical factors for women beginning strength training in their 40s, more important than any single protocol
• Michelle describes her 15-year battle with bulimia and anorexia as wasted energy that could have been directed toward achievement, and now coaches clients on nervous system regulation to prevent disordered eating patterns
• Basic functional movements—carrying, pushing (like wall pushes or push-ups), and overhead pressing—are highlighted as foundational for maintaining independence and preventing frailty in later decades
