Speaking of exercising, it seems MBLAQ's Lee Joon loves working out as well. On the January 22nd edition of MBC's Happy Day, there was a segment showing Lee Joon working out at a gym. http://www.youtube.com/watch?v=i20xfRZ5b94 It seems Lee Joon loves showing off his body. If you can recall, a few weeks ago he showed off his back and his abs a few months before that. Thanks to LJ for the tip!
