Many women think cardio is the fastest way to lose weight. But after 40, that’s not always true.
The goal isn’t just to burn more calories during a workout. The real goal is to protect and build muscle.
Muscle is what keeps your metabolism higher. The more lean muscle you have, the more calories your body burns throughout the day.
When people rely mostly on cardio, a few things often happen. You can actually start losing muscle, not just fat. And when you lose muscle, your metabolism slows down, which makes fat loss harder over time.
Strength training does the opposite.
It tells your body to keep or build muscle while burning fat. And another big benefit is that your body continues burning calories even after the workout is finished, sometimes for up to 24–48 hours.
So if you had two options:
1. Strength train 3 times per week
2. Do cardio every single day
In most cases, the strength training option will lead to better fat loss results, especially for women over 40.
