About the show

Muscle Science for Women is a weekly podcast for women who want to build muscle, get stronger, improve their nutrition, and understand what their bodies actually need, especially in their 40s and beyond. Hosted by Rachel Gregory, MS, CNS, CSCS, and Ashleigh VanHouten, each episode takes a question women are asking and breaks down what the research says, what matters in real life, and what you can actually do with that information. Rachel is a nutritionist, strength and conditioning specialist, and the founder of RG Fitness. Ashleigh is an author, coach, and former nationally ranked natural figure competitor and powerlifter. Together, they bring science, coaching experience, personal stories, and plenty of honest conversation to topics that are often confusing, oversimplified, or buried under a mountain of internet bullshit. You'll hear conversations about strength training during perimenopause and menopause, hormone replacement therapy, bone density, body composition, and how to train now so you can still be strong at 80. Rachel and Ashleigh also dig into the fundamentals beneath it all, including protein, fat loss, maintenance phases, muscle growth, rep ranges, cardio, training zones, GLP-1s, fasting, gut health, pelvic floor health, emotional eating, and the habits that make progress sustainable. This is not about chasing perfection or following one rigid plan. It's about understanding the why behind training and nutrition so you can make better decisions for your body, your goals, and the season of life you're in.
