Muscle Mastery
Muscle Mastery: Your #1 Fat Loss Tool and Tissue of Longevity
Show me the 80-year-old that feels like they have too much muscle!
Muscle is the cornerstone of healthy aging, sustained weight loss, and living an independent life. But building muscle isn’t accidental—it doesn’t come from a gym membership or random lifts. Instead, it’s a specific skill that demands deliberate effort, with every pound earned through precision and hard work.
This program teaches you the art and science of muscle building. Whether your goal is to support fat loss, enhance appearance, boost strength, or harness muscle as the ultimate tool for longevity, Muscle Mastery covers the science, nutrition, and practical techniques you need. Get ready for a fascinating, inspiring, and efficient journey that equips you with the exact methods to build muscle and maximize your time and energy.
Build Muscle. Burn Fat. Age Strong.
Why Muscle Mastery Matters
The idea that men build so much more muscle than women is misleading—it’s largely about different starting points. Many women have more slow-twitch muscle fibers, which are less prone to growth. Progress is slow for everyone after the initial “newbie gains.” But the end goal is one we all should want, because muscle is:
- The #1 fat loss tool
- The tissue of longevity
- The foundation for confidence, function, and independence

A Word from Joanne Lee Cornish
I’ve never met an 80-year-old who wished they had less muscle. Strength, energy, resilience, and fat loss all come back to one thing: muscle. That’s why I created Muscle Mastery—to give you the structure, clarity, and strategy to build what truly sustains you.
This isn’t random workouts, and it isn’t a quick fix. It’s about learning the exact science of muscle so you can apply it for life. If you’re ready to understand it, build it, and keep it—this is the program for you.
