Myth: “Cardio is the best way to manage my weight.”
While cardiovascular exercise burns calories and improves heart health, it’s not the only—or even the most effective—tool for weight management.
Diet, strength training, and cardio-based exercise all contribute to weight management. However, it is strength training, not cardio-based exercise, that helps build lean muscle mass, which increases your resting metabolic rate. That means you’ll burn more calories even when you're not exercising. Learn more about why muscle mass matters and how to keep it.
A balanced fitness routine that includes both strength training and cardio will support fat loss more effectively than endless treadmill sessions alone.
