Hi Friends~
Did you see this?
Astronaut Christina Koch re-acclimating to gravity after the Artemis landing. After only 10 days in space, she struggled to walk. It was a stark, public reminder of what happens when we lose the load.
Since the first Apollo mission in 1969, scientists have known that the weightlessness of space accelerates muscle wasting (age-related sarcopenia), bone loss, and a decline in cardiovascular fitness. It’s essentially aging at warp speed.
The solution in space? Daily high-intensity cardio combined with heavy resistance training.
Does that sound familiar? It’s the exact same “space protocol” I advocate for you right here on Earth.
Strength and cardio training are the most effective methodologies for mid-life and older bodies. They allow us to function against the constant pull of gravity, crush stereotypes of age-related decline, and achieve feats of prowess that fire us up—like 74-year-old Ginny MacColl, the Guinness World Record holder for the oldest competitive female ninja athlete.
And me!
Resistance is Our Friend
It doesn’t matter what your daily demands are or what you aspire to do: Strength is essential for life. Declining muscle mass, loss of power, and failing coordination are the strongest predictors of frailty, loss of independence, and early death. To offset the natural “decay” of aging—harsh word, I know, but true—we have to push back.
Here is how you do it efficiently:
-
Ditch the Gazillion Reps: It isn’t time-efficient to lift light weights for 50 reps. Aim for the “minimum effective dose”: 5 to 12 reps at an effort that is honestly challenging.
-
The Progress Principle: When 12 reps start to feel easy, don’t add more reps. Add weight. Use dumbbells, kettlebells, or your own body weight in more challenging angles.
-
Cardio as Insurance: Low cardiovascular fitness is a major predictor of all-cause mortality. If a 30-minute brisk walk leaves you breathless, that’s your signal to ramp up.
You don’t have to run for hours or live in the gym. For most people, 3 or 4 sessions a week at home, or wherever you are is the sweet spot to stay “gravity-ready.”
The Bottom Line
I’m often asked: “How do I know if the weight I’m using is effective?”
My answer is always: Effective for what? Is it for carrying your grandkids? Lifting some soil bags in your garden? Excelling at a physical job? Reaching a competitive goal? Or simply the ability to play and enjoy your life without restriction?
Building muscle and developing power, and cardio fitness is essential for everyone.
The way you do it is for you and for your life.
I got you. Let’s do it.
