Why Intensity Matters
Most people think all cardio minutes are equal.
They're not.
A recent study of more than 73,000 people found that 1 minute of vigorous exercise provided health benefits similar to about 4 minutes of moderate exercise in reducing all-cause mortality (your overall risk of dying from any cause).
In some health outcomes, the difference was even greater.
What does that mean in the real world?
10 minutes of hard intervals ≈ , 40 minutes of moderate cardio for longevity benefits
15 minutes of hard intervals ≈ , 60 minutes of moderate cardio
20 minutes of hard intervals ≈ , 80 minutes of moderate cardio
This doesn't mean walking is useless, but be sure to put some pace on the walk.
The message is simply that intensity provides a bigger return per minute invested.
That's one reason we include interval-based conditioning in our programming. The goal isn't to spend as much time as possible exercising. The goal is to create the biggest positive adaptation in the time you have available.
For busy people, that's an important distinction.
Work smarter, not just longer.
