Megastar Amitabh Bachchan, who seems quite fit and agile at 72, is pumping some extra iron in the gym these days. He says it has nothing to do with ‘medical’ needs, but for his desire of a ‘refined body,’ which would assist him in one of his ‘future film projects.’ “The work out goes well. The difference shall hopefully be of notice by another 3 months. That is one ‘hellava’ long time to wait for body development,” Big B wrote on his blog.
