A group photo of 2AM at the gym was revealed.

Chang Min posted on his Twitter, "Everyone working out together! It's been a while," along with a photo of 2AM members working out together at the gym.

The members dressed in comfortable workout clothes are each on a running machine. Chang Min is making a silly face while Jo Kwon is moving so fast that you can't even see his feet.

Internet users who saw the photo commented, "Where are his legs?", "Who took the photo?", and "This is so good to see.”
