For fans who've wondered and admired Jang Hyuk's luxurious and muscular body, Jang Hyuk recently revealed the steps in making his muscular body on the June 29th broadcast of SBS's 'One Night of TV Entertainment'. His first secret was in making the arms muscular. Jan Hyuk revealed, "I always carry 10 kg. (22 pounds) worth of weights in the car." He showed how he endured holding the weights 90 degrees as he did 1 set around 10 times with the 10 kg. weights . He explained, "Your endurance gets better and the strength you need also increases as your muscles form." He also suggested turning the dumbbell for 10 sets with 50 reps in a day to strengthen one's wrists. His second secret was in making the abs. Jang Hyuk suggested, "Every day, try to perform 100 high leg kicks. To make the abs toned you have to always be on the move. When you hold your legs up, you're strengthening the stomach." Jang Hyuk's last bonus secret was in creating a well balanced body as a practitioner of Jeet Kune Do, which was Bruce Lee's martial art philosophy. Source: Nate
