Actor Kim Ji-hoon recently expressed admiration for co-star Kim Hye-soo’s enviable physique.
In a video titled "[Warning] A feast of talk more provocative than an affair!" uploaded to the YouTube channel 'PDC'—featuring Kim Hye-soo, Jo Yeo-jeong, Kim Ji-hoon, and Kim Jae-chul—the cast shared a meal after a screening. "Kim Hye-soo really eats a lot. That surprised me," Kim Ji-hoon noted.
As Kim Hye-soo laughed, Kim Ji-hoon continued, "When you watch the drama, there's a scene showing her silhouette in lingerie, and she has absolutely no belly fat." Co-star Kim Jae-chul chimed in, "It reminded me of Madam Jeong from Tazza."
Kim Ji-hoon added, "She is so slim, tall, and lean. Watching her made me feel like I still don't truly understand the human body. It left a deep impression because her physique defies what I consider common sense."
Water-based workouts reduce joint strain while boosting calorie burn and muscle strength
As Kim Ji-hoon observed, Kim Hye-soo maintains a firm, toned figure without excess fat even at age 55. She has occasionally shared workout updates on social media, drawing attention for consistently engaging in aquatic exercise wearing a fitted bodysuit.
Exercising in water—such as walking or riding an underwater bike—uses buoyancy to relieve joint pressure while strengthening muscles across the entire body. Because water provides continuous resistance, performing movements underwater recruits more muscle fibers than doing the same exercises on land. It also enhances cardiovascular endurance and accelerates calorie expenditure.
Aquatic workouts further promote blood circulation and help alleviate swelling. With regular practice, water-based training improves balance and builds lower-body strength. Middle-aged women, who frequently experience reductions in muscle mass and bone density alongside joint strain in the knees or lower back, can use aquatic exercise as a safe, effective method to build stamina and manage weight.
Proper posture, water temperature, and depth are essential for safe exercise
Rather than starting with high-intensity or lengthy workouts, individuals should begin slowly with brief sessions suited to their personal fitness levels. Wearing dedicated water shoes is recommended to prevent slips and falls on slick pool surfaces.
Posture can easily break down in the water, leading to excessive pelvis swaying or lower-back arching during movement. To maintain stability while walking or cycling underwater, exercisers should engage their core and glutes to keep the upper body steady.
Water temperature and depth are also critical variables. Cold water can cause body temperature to drop, leading to muscle stiffness and heightened fatigue. An ideal water depth is around the solar plexus; if the water is too deep, buoyancy can excessively reduce exercise intensity.
