BLACKPINK’s Jisoo recently captivated fans by showcasing her defined core. On the 23rd, Jisoo shared editorial photos and behind-the-scenes glimpses on social media, posing against a mysterious cave backdrop. Dressed in a white bralette and a mermaid-style long skirt, her slicked-back hair and bold eye makeup created a captivating vibe, a departure from her signature "pure and innocent" image.
What particularly drew attention was the firm, clearly visible muscle definition beneath the sheer bralette. Jisoo has consistently displayed a healthy, athletic physique during BLACKPINK concerts and fashion editorials. Unlike the "waif-ish" thinness often associated with girl groups, Jisoo has maintained a lean yet toned figure through a dedicated Pilates practice she began in 2022.
As a member of the global powerhouse BLACKPINK, Jisoo is also cementing her status as a "rom-com queen" following the success of her Netflix series Monthly Boyfriend, which reached No. 1 globally. With a packed schedule—including BLACKPINK’s full-group comeback last month with their third mini-album DEADLINE—we take a closer look at the Pilates routine she uses to manage her stamina and physique.
Sculpting a Slim Physique with Pilates
Jisoo has practiced Pilates three to four times a week for five years. Her deep commitment to the discipline—once stating in an interview, “I’m addicted”—has led to noticeable changes in her body shape, earning her the nickname “Pilates Princess” among fans.
Pilates is an exceptional workout for creating a long, lean silhouette by strengthening the core muscles. Through movements like roll-ups and single-leg stretches, the practice stimulates both the rectus abdominis and the transverse abdominis simultaneously. Unlike standard crunches, Pilates activates the deeper core layers, resulting in a firm, defined abdominal line.
The practice also refines the thighs, glutes, and upper body through core stabilization. By correcting posture and addressing muscle imbalances, it improves waistline definition and pelvic alignment. According to a study from Marymount University, practicing Pilates three times a week for three months can result in a 2% decrease in body fat. Experts emphasize that precise form and regular breathing are key; professional guidance is recommended to achieve these results without injury.
To amplify weight loss, Jisoo often combines Pilates with high-intensity cardio, such as boxing with her fellow members, or flying yoga for full-body stretching.
High-Intensity Performance and Calorie Burn
As a top-tier group performing in stadiums for crowds of up to 60,000, BLACKPINK’s stage presence is a workout in itself. Running across massive stages naturally aids in weight management.
Typical girl group dance practices are high-intensity cardio sessions lasting three to five hours a day, burning between 400 and 600 kcal per hour. World tour concerts, which often run for three hours plus extensive rehearsals, build balanced strength in the core and limbs. When combined with the refining effects of Pilates, this creates a synergy that adds on-stage stability and builds significant cardiorespiratory endurance. However, because of the high physical demand, proper rest and nutrition remain essential to prevent injury.
