What is the main difference between cardio and strength training activitys?

The main difference between cardio and strength training lies in their primary focus and benefits. Cardio exercises, such as running or cycling, primarily enhance cardiovascular endurance and burn calories by elevating heart rate. In contrast, strength training, like Weightlifting, focuses on building muscle strength and mass by using resistance. Both types of exercise are important for overall fitness, but they target different aspects of physical health.
