Broadcaster Jonathan sheds pounds with nightly runs

South Korean broadcaster Jonathan has revealed a significantly slimmer physique, attributing his transformation to a consistent running routine. Jonathan shared photos on his social media account on August 26, documenting his late-night 5km run. The images show him post-exercise, with his face and arms glistening with sweat, yet he maintained a bright smile for the camera.

This recent update contrasts with Jonathan's previous public discussions about his weight. In 2022, during an appearance on the KBS 2TV entertainment program 'Godfather,' he openly discussed his struggles with weight gain. At the time, he stated, "I've gained so much weight lately. I'm 106 kg right now," adding, "As of August last year, I was 86 kg."

Jonathan's chosen method of exercise, running, is recognized as a highly effective form of aerobic activity. The American Heart Association (AHA) recommends adults engage in at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic exercise per week. Running is cited by the AHA as a prime example of vigorous activity, characterized by a significant increase in heart rate and breathing that makes conversation difficult.

For individuals new to exercise or those with lower activity levels, the AHA advises a gradual approach. Starting with walking or short runs and progressively increasing the duration and intensity is recommended over immediately undertaking high-intensity workouts. The AHA also suggests increasing moderate activity to 300 minutes per week for enhanced health benefits, emphasizing that exercise volume should be tailored to individual fitness and health conditions.
