Lee Joon revealed his abs through "Star King."
On the "Star King" (MC Kang Ho Dong) episode that aired on the evening of August 28th, the first set of challengers of the yo-yo came for a check-up on Star King. The first set challengers that succeeded in their diet appeared on the studio wearing a bikini.
Compared to the first set challengers that found confidence while dieting, the second set challengers showed envy towards the first set. Sean Lee demonstrated a few exercise movements to the jealous second set.
Health trainer Sean Lee showed frog exercise, which can help lose thigh-weight, and MBLAQ's Lee Joon demonstrated the perfect example, receiving applause from Sean Lee.
To Lee Joon's perfect demonstration, the writers and cast demanded Lee Joon's abs, and after hesitating shortly, saying, "I quit exercising for three months," he revealed his same as ever chocolate* abs, and received more applause.
