What motivates you to take care of your body? For gagman Lee Ji Sung, who is a regular on MBC's TV show 'Comedy Road', it's his love for his self, of course, and his wife-to-be.

Cue the "Rocky Theme Song" and let the epic work-out montage begin.

Phew, that looks tough! All this working for the love of his life, who he will be marrying on November 15. His bride-to-be is a non-celebrity who works in the cosmetic industry. The two lovebirds met 5 years ago, when Lee Ji Sung was struck by love at first sight after seeing her on the streets. He begged her for just one date, and as a result, is now engaged to his lovely lady.

Ahead of the wedding, as well as the wedding photoshoot, Lee Ji Sung has decided to shed some weight. He recently shared via SNS the results of his diet and exercise routine. Originally weighing 118 kg (approx. 260 lbs) he now weighs 77 kg (approx. 170 lbs) and has thus lost around 40 kg (or 90 pounds). After weeks of working out, he now greets both the public and his fiancee a fit, sculpted body and an upgrade in confidence! 

What do you guys think of his transformation?
