Kim Hye-soo, 56, Shares Balance-Testing Workout Videos

Veteran actress Kim Hye-soo gave fans a look at her workout routine, taking her exercise onto the water. On Oct. 28, she posted several exercise videos on her social media account without a caption.

In the clips, she is working out in an indoor swimming pool. She climbs onto a mat floating on the water and begins a core workout. First, she does a twist plank. She supports her body with her arms and twists her upper body. Then she lies on her back and moves into bicycle crunches, alternately bringing her legs back and forth.

Keeping her balance on the floating mat proves challenging. It rocked every time she moved. Still, she held her form anyway and stayed focused through each move.

Her steady control drew praise from viewers. It also hinted at the strength she has built through years of regular exercise.

Born in 1970, Kim Hye-soo turns 56 this year. She often shares workout clips on social media, giving followers a glimpse at how she takes care of herself as part of her daily routine.

This year also marks the 40th anniversary of her debut. She started her acting career in 1986 with the film "Kam-bo." Since then, she has appeared in films such as "The Thieves," "Default" and "Smugglers," along with dramas including "Signal," "Juvenile Justice" and "Under the Queen's Umbrella."

Most recently, she starred in "The Affair Was Just the Beginning" (Jigeum Bullyuni Munjega Animnida), a series released on the Korean streaming platform Coupang Play. She played Kyung-hee, the head of an interior design company who is also a popular influencer.

Four decades into her career, she is still putting in the work. Kim continues to show the same dedication to her craft and to her workouts. Even when the mat beneath her refuses to stay still.
