This week on The Weekly Riff, Louise Green dives into one of the biggest debates currently happening in women’s fitness: should women over 40 be lifting heavy weights, or can lighter weights with higher reps deliver the same benefits?

Inspired by the ongoing conversation between leading experts Dr. Stacy Sims and Dr. Lauren Colenso-Semple, this episode explores the science behind strength training, muscle growth, menopause, aging, and performance while cutting through the noise that often leaves women feeling overwhelmed and confused.

But this conversation goes far beyond reps and sets.

Louise challenges the fitness industry to confront a larger issue that rarely gets enough attention: millions of women are not struggling with optimization, they are struggling with consistency, confidence, and access. In a culture where many women feel judged, excluded, intimidated, or unsupported in fitness spaces, the “perfect” workout program becomes irrelevant if people cannot sustain movement long term.

Inside this episode, Louise breaks down:

• Heavy lifting versus lighter weights
• Menopause and resistance training
• Muscle hypertrophy and aging
• Bone density and fast twitch muscle preservation
• Progressive overload explained simply
• Accessibility and inclusivity in fitness culture
• Motivation, consistency, and long term adherence
• Redefining what “successful” fitness looks like for women over 40
