[MyDaily = Reporter Kim Ji-woo] Former Jewelry member Lee Ji-hyun showed off her toned physique.

On the 24th, Lee Ji-hyun wrote on her personal social media, “At my age, you can tell right away if I stop working out. I was so busy with yesterday’s opening that I couldn’t fit in a workout, and my back ached so badly I couldn’t sleep. This morning I got the kids to school early, did core exercises, and then went to work. If you’ve seen my feed, come by. I have deep respect for all beauty professionals.”

The accompanying video shows her doing a mix of weight and core exercises at home. She moves through barbell-plate work, side planks and back-arch motions, demonstrating both balance and strength. Her flat, well-defined midsection, visible abs and toned arms point to a consistent training routine.

Lee Ji-hyun is raising one son and one daughter on her own after two divorces. She recently passed the national cosmetology licensing exam and has started working at a newly opened salon.
