4. Arjun Kapoor: The handsome hunk who looks absolutely ravishing in all his movies was once 140 kilos. The actor could only fly business class owing to their wider seats. He could not run for more than 10 seconds and was always lethargic, temperamental and grouchy. And, he even suffered from asthma at the age of 22.With the help of his mentor Salman Khan, Arjun worked out and was also under strict dietary plans. His work-out regime includes cardio and CrossFit workout.
