48-year-old Chae Jung-an, visible ribs and a cinched waist…thanks to this at-home workout?

Actress Chae Jung-an, 48, shared what she looks like while working out at home.

On the 1st, Chae posted several photos along with the message, “My New Year’s goals for 2026: be happy with my beloved family, work out diligently, enjoy lots of delicious food in a healthy way, read books, and study English too.”

In the photos, Chae is working out at home in a crop top and leggings. As she rides an indoor stationary bike and does pull-ups, she drew attention for her firm, toned physique with little body fat.

A stationary bike makes it easier to keep up cardio consistently—even at home

The stationary bike workout Chae chose for her at-home routine has the advantage of letting you do steady cardio indoors without being limited by the weather or outdoor conditions. Because it places less impact on the knees and ankles, it tends to be gentler on the joints, and it can help improve cardiorespiratory endurance and reduce body fat.

Because the intensity is easy to adjust, everyone from beginners to experienced exercisers can tailor it to their fitness level. You can also ride while watching TV or listening to music, which can make it easier to stay consistent without getting bored.

However, if the saddle height or handle position doesn’t fit your body, it can lead to lower-back or knee pain. It’s best to adjust the saddle so that when the pedal is at its lowest point, your knee does not fully straighten, and to start at a low intensity for 10–15 minutes before gradually increasing the duration.

A doorway pull-up bar lets you train upper-body strength without needing extra space

Next, Chae did a hanging exercise using a pull-up bar installed in a doorway. Doorway pull-up bar workouts can effectively strengthen upper-body muscles without requiring a large dedicated space or expensive equipment.

They primarily work muscles across the upper body, including the latissimus dorsi, biceps, and forearm muscles. Because they use your body weight, they can support weight management while building strength. With high efficiency in a short amount of time, they’re well-suited to at-home training for people with busy schedules.

However, if the doorframe is weak or the bar is not installed properly, it can come loose during exercise and cause a fall. Before working out, be sure to check the doorframe material and the stability of the installation.

It’s best to warm up on the stationary bike, then do pull-up bar exercises

If you do both exercises in one session, it’s generally recommended to start with the stationary bike and then move on to pull-ups. Because the stationary bike is an aerobic exercise that gradually raises body temperature and increases blood flow, it can serve as a warm-up before strength training.

After that, doing pull-ups can help reduce stiffness in the shoulder and arm joints, lowering the risk of injury. In particular, warming up with a light 5–10 minutes on the stationary bike, then doing pull-ups, and finishing with an easy stationary-bike cooldown can help balance fatigue and recovery.
