2AM Jo Kwon's slim figure may be misleading, but once he lifts up his shirt, his dazzling body has the powerful impact of causing nosebleeds. Adding onto his chiseled six pack, 55kg (121 pounds) Jo Kwon could easily lift up heavy weights that weigh 80kg (about 176 pounds). A short video clip of this feat is becoming a hot topic. With the title 'Jo Kwon's success clip of his 80kg bench press', Jo Kwon's intense working out mode could be seen. Netizens have commented:

"I think it's amazing that 55kg Jo Kwon could easily lift up 80kg weights.

"Although Jo Kwon may look weak and skinny in figure, he has a lot of muscles" "He has been working out for a couple of years now. Despite his packed schedule, he always squeezes in 1~2 hours to work out" "Jo Kwon's trainer filmed the clip"
