Son Na-eun’s Fitness Routine.
Son Na-eun recently shared several photos on her Instagram, once again flaunting her signature slender physique. As a fitness icon, her dedication to maintaining her body is widely admired.

According to her official profile, Son stands 168 cm tall(5'6" tall)and weighs 48 kg(106 lbs). Her secret? Regular workouts on the “stairway to heaven” — also known as the stepmill. She once even shared a photo proving she completed 1,000 steps on the machine, demonstrating her intense commitment to fitness.
Why the Stepmill Works Wonders
The stepmill simulates climbing an endless staircase, much like a treadmill but with a continuous upward motion. It’s an extremely effective workout, capable of burning around 100 kcal in just 10 minutes. Not only does it increase heart rate, but it also enhances maximum oxygen uptake, which is crucial for improving cardiovascular function and stamina.
When maximum oxygen uptake improves, blood flow increases, boosting overall endurance and heart-lung function. The stepmill is also excellent for building lower body strength, targeting muscles in the thighs, glutes, and calves. Maintaining proper posture while using the machine can also help strengthen core muscles. Unlike running, climbing the stepmill is easier on the joints, making it a safer option for many fitness enthusiasts.
Despite its benefits, overdoing it too quickly can lead to injury. It’s important to start slow and gradually increase intensity based on individual fitness levels.

Key tips to remember:
Hold the handrails lightly without leaning your body weight on them. Push off the steps using the entire foot to avoid putting strain on the ankles. Avoid bending too far forward or standing overly stiff. Engage your core as you climb to improve core strength while minimizing pressure on the lower back.
With consistency and proper form, the stepmill can be a game-changer for anyone looking to improve their endurance and build lower body strength—just like Son Na-eun.
