In interviews with the 'SWEET HOME 2' cast, actresses Go Min Si and Lee Si Young revealed that Song Kang often asks other cast members if he looks different after training.

The two beautiful actresses joked about how Song Kang "looks at himself in the mirror" and "shows off his muscles" during breaks from filming.

Although they acknowledged the actor's transformation from a teenager to an adult man in the new season of 'SWEET HOME', other cast members actually caught attention with their muscles, namely Lee Si Young.

Song Kang proved Lee Si Young's dedication to exercise by revealing that she always brings dumbbells and uses them every time they prepare for filming.

Intense training by Lee Si Young paid off as Song Kang was very impressed with her back muscles. The actor said, "Lee Si Young's back muscles always look fiery."

But Song Kang is not the only 'SWEET HOME 2' cast member surprised by Lee Si Young's determination to stay fit. Jung Jin Young also expressed his admiration for Lee Si Young's appearance.

Jung Jin Young, who revealed that he has the same trainer as Lee Si Young, was amazed to learn that the actress can "lift very heavy weights."

Although she is now married and has a child, Lee Si Young proves that she can still maintain her physique in the best condition.

As is known, Lee Si Young not only regularly exercises at the gym, but also has a hobby of extreme sports such as mountain climbing, which requires a fit physique.

Seeing Lee Si Young's tight stomach and muscular arms, it's no wonder it makes everyone jealous, including actors like Song Kang and Jung Jin Young.
