How Women Should Train Differently: Insights from Dr. Stacy Sims
Understanding how women’s bodies age is a critical step toward building more effective fitness routines. In a recent episode of SuperAge, Dr. Stacy Sims, a leading expert in women’s health and exercise physiology, explains why women need a different approach to fitness, especially as they reach their 40s and beyond. Her key insight? Women are not small men—and their workout plans should reflect that.
The Role of Hormones
From puberty to menopause, hormonal changes have a profound impact on how women gain muscle, lose fat, and recover from exercise. For starters, Dr. Sims stresses that perimenopause is a particularly pivotal time, as many women experience significant changes in muscle mass, bone density, and metabolism. While men’s bodies age in a more predictable, linear fashion, women undergo a sharp physiological shift during perimenopause that requires more tailored fitness strategies.
Why Heavy Lifting is Critical
According to Dr. Sims, women over 40 must shift from low-weight, high-rep routines to power-based strength training. Lifting heavy with low repetitions builds lean muscle, improves bone density, and helps offset the decline in strength that comes with age. “If you’re still using those pink dumbbells, it’s time to rethink your strategy,” Dr. Sims says.
High-Intensity Workouts for Women
Many fitness enthusiasts tout the benefits of Zone 2 training for improving fat metabolism, but Dr. Sims says women need to focus more on high-intensity intervals. Women are already metabolically flexible. With this in mind, high-intensity interval training (HIIT) and sprint interval training are far more effective for maintaining muscle quality, especially during perimenopause.
The Takeaway
Dr. Stacy Sims’ message is clear: To age healthfully, women must train differently from men. With the right approach—heavy lifting, intense intervals, and smarter recovery—women can optimize their strength, health, and longevity as they age.
By applying these insights, women can revolutionize how they approach fitness during their later stages of life, ensuring they stay strong and vibrant for years to come.
