On her YouTube channel “Study King Jin Genius Hong Jinkyung,” model and TV personality Hong Jin-kyung shared her fitness routine under the title “Hong Jinkyung’s Secrets to Maintaining a Size 44 at 180cm.”
Hong revealed, “I have a photoshoot tomorrow, and I’m concerned about my weight right now. Since it’s crunch time, I started my routine early in the morning.”
In the video, Hong heads to the swimming pool, explaining, “I go back and forth ten times each. I’ve never formally learned swimming, and my form isn’t great, but I give it my best.” She also demonstrated her unique exercise technique, walking in the water. “I do this when going across—it helps burn fat,” she said, moving like she was doing water aerobics.
After swimming and a meal, Hong Jinkyung headed to Bukaksan Mountain. “If there’s nothing special going on over the weekend, I go hiking,” she shared, scaling rugged trails without hesitation. At the peak, she took a moment to enjoy the breathtaking view and meditate.
Swimming Burns Calories and Builds Strength
Hong Jin-kyung’s chosen workout, swimming, is a full-body aerobic exercise that can burn approximately 500 kcal per hour. For comparison, walking burns around 300 kcal and cycling about 360 kcal per hour, making swimming particularly effective for weight loss.
Swimming also strengthens muscles. The freestyle stroke builds core and back muscles and tones the arms. Backstroke strengthens the back and shoulder muscles, while the breaststroke targets lower body muscles.
While swimming is beneficial for overall health, there are also precautions to consider. Swimming pools are often chlorinated, which may irritate those with sensitive or pre-existing skin conditions. Additionally, the repeated shoulder rotation can lead to shoulder impingement or rotator cuff injuries if overused. If shoulder pain occurs, it’s essential to rest, and if severe, seek medical attention.
Mountain Hiking Effective for Fat-Burning, with Caution on Descent
The second exercise Hong frequently does is mountain hiking. Hiking is a high-calorie-burning aerobic exercise that can burn approximately 430-550 kcal per hour on moderately steep trails. Hiking can also help reach 70%-80% of maximum heart rate, a zone where body fat burns rapidly.
However, it’s important to take caution for those with limited activity or existing joint issues in the knees or lower back, as descending can strain ligaments supporting the spine and joints. Sudden turns or landings on the descent can twist joints, potentially damaging cartilage.
To safely descend, walk at about half the speed of a flat surface, avoid large strides or running, and use a knee brace and cushioned insoles to reduce impact on the knees and ankles. Hiking poles are also helpful for maintaining balance and distributing load away from joints. Adjust the poles short when going uphill and long when descending. Additionally, warm up thoroughly to improve joint flexibility, and ensure that your backpack weight does not exceed 10% of your body weight to minimize pressure on your lower back during descent.
