Women Don't Need Special Training Programs Says Exercise Physiologist

This episode fundamentally challenges gender-specific fitness marketing by presenting evidence that women and men respond identically to resistance training. Dr. Lauren Colenso-Semple, an exercise physiologist, explains that muscle protein synthesis, growth responses, and adaptation mechanisms are essentially the same between sexes at the cellular level.

The primary difference lies in baseline muscle mass, established during puberty when testosterone surges increase male muscularity. However, once training begins, both sexes gain similar relative muscle size. Even testosterone levels within normal ranges don't predict training responses - a man with 400 ng/dL versus 600 ng/dL won't see dramatically different muscle growth.

For practical application, she recommends full-body workouts 2-3 times weekly, performing 2-4 work sets per muscle group within 1-2 reps of failure. Any rep range from 3-20 can stimulate growth if taken to near-failure, though lower reps require more total sets to match volume. Rest periods should be 2-3 minutes, with compound movements like squats and deadlifts forming the foundation.

The longevity implications are significant: resistance training builds muscle mass that serves as a "savings account" against age-related sarcopenia. Starting earlier provides greater long-term benefits, but muscle growth remains possible even when beginning at age 70. This challenges the cultural narrative that has historically discouraged women from serious strength training, potentially limiting their healthspan and functional capacity in later life.
