You’ve probably heard it: to build strong bones and muscle mass, you need to lift heavy. But what does “lifting heavy” really mean? And is it the only way to get results?
In this episode, I break down the confusion and intimidation around lifting heavy, share a real-life story from a client who overcame her fear of weights, and explain how perceived exertion is just as important as your 1-rep max.
We’ll explore what the research says about lifting heavy versus moderate and light loads for bone density, muscle strength, and overall resilience. Spoiler: you don’t have to lift the heaviest weights in the gym to see results!
Here’s what you’ll learn:
🔸 Why “heavy” is relative — and how to know when you’re lifting heavy for you.
🔸 The real difference between “muscle burn” and “muscle failure.”
🔸 How lighter loads can still be powerful for bone and muscle health — especially if you’re newer to strength training.
🔸 Why progressive overload matters and how you can progress without chasing heavier and heavier weights forever.
🔸 My simple strength progression framework to help you meet your body where it’s at, and move forward with confidence.
