Lee Sung Kyung’s Workout Rules for a Slim Figure
In singer Im Seulong’s program OngStyle, Lee Sung Kyung revealed that she has maintained her workout routine for 15 years, despite her busy schedule. She particularly focuses on exercises that tighten her abdominal muscles, enhance her body’s firmness, and maintain her well-proportioned figure.

She adheres to a strict diet and exercise regimen to maintain her ideal physique.
1. Advanced Plank – The Ultimate Abdominal Workout
Lee Sung Kyung’s favorite exercise is the plank, which not only helps her maintain a slim waist but also improves her endurance and supports her dance moves in musicals. Her plank routine includes:
- Basic Plank: 30 seconds
- Hip-dipping Plank (each side): 30 seconds
- Plank with Hip Movement: 30 seconds
- Rest for 30 seconds, then continue with one-arm plank on each side
This exercise not only tightens the abdominal muscles but also strengthens the core, improving the body’s flexibility and balance.
2. The “drawing-in” method for a slender waist
In addition to planks, Lee Sung Kyung practices the drawing-in exercise, a method that activates the transverse abdominis muscle, effectively tightening the waist from within. This exercise helps reduce post-meal belly bloating and defines the waistline.
How to perform it:
- Breathe in deeply through your nose, feeling your stomach expand.
- Breathe out slowly, sucking in your stomach as much as possible and holding for 5-10 seconds.
- Repeat this process 10-15 times daily.
By consistently performing this exercise, Lee Sung Kyung effectively controls her figure without resorting to intense workouts.
