Looks like 2AM's Changmin isn't the only person working hard to obtain a beach-ready body.

Actor Jang Geun Suk recently revealed a photo of himself sweating bullets trying to create a defined six pack.

The actor recently shared the photo above via his Twitter page and wrote, "It's begun! Operation Get Rid Of Baby Stomach! Will Geun Suk be able to play guitar at the CRI Show with his shirt off? Da dum!"

With his long hair tied back, an exhausted-looking Jang Geun Suk took a proof-shot of himself at what appears to be the gym.

Fans did not seem to object to the idea of a six pack as they wrote, "I'm happy just imagining you playing the guitar half naked", "You will be beyond perfect once you have a six pack", and "So good to see you are constantly challenging yourself!"

In related news, Jang Geun Suk will be launching his Asia Tour 'THE CRI SHOW 2', starting with a show in Seoul and traveling to 4 cities in Japan, as well as China, Southeast Asia, and more.
