Description
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.

Ashleigh and Rachel go through six major food swaps for fat loss for anyone who wants to make more mindful, empowered, and reasonable choices in their diet. Ashleigh highlights the differences between a healthy diet and a fat loss diet; Rachel shares the frozen blueberry cereal she has been making, and they also talk about smart swaps that can reduce calories without reducing satisfaction and flavor, and how to avoid hidden calories you may not even know you're consuming.

Then the ladies answer two listener questions: whether three, ten-minute blocks spread across a day can build strength, and how to adjust training through heavy cycles, low iron and deep fatigue.
