No matter how quiet a gym is, you'll almost always see someone on a treadmill. That's because running or walking is a great way to exercise. Running in particular offers numerous benefits, such as improving your cardio fitness and strengthening bones. Plus, because it demands more energy than walking, it can aid in weight loss.
That said, there's no getting around it, if you're new or returning to exercise, running is hard. The first time I tried running as an adult I made it to the end of the street before I had to stop—totally out of breath.
