Shahrukh Khan to get athletic in Don 2

After losing weight for his home production, Ra. One, Shahrukh Khan will pile it on for Farhan Akhtar's Don 2. The man aiding SRK to gain muscle is fitness trainer Prashant Sawant, who had helped him build his six-pack abs for Om Shanti Om. Incidentally, Prashant is also training Boman Irani, SRK's co-star in Don 2.

Says a source, "SRK's role in Don 2 requires him to not just be fit but to have a tough, athletic and lean body -- something that can help him do high-intensity stunt sequences effortlessly. Prashant Sawant, his trainer of 10 years, is helping him achieve that. For over a month now, the actor has been undergoing extensive weight training along with a high-protein diet

that helps build muscle mass."

Khan's exercise routine includes working out rigorously at his gym at home for an hour. "He is concentrating only on weight training with no cardio. But all the exercises are done keeping his shoulder injury in mind. His diet includes eggs and steamed or grilled chicken." Don 2 producer Ritesh Sidhwani says, "Shahrukh is not beefing it up for Don 2. He's just building on some muscle for his different image in the film. He lost a lot of weight for Ra. One and will be putting on some for Don 2."

Currently, Ritesh and Farhan are in Berlin scouting for locales and beginning pre-production work. Riteish says, "A major part of Don 2 will be shot in Berlin. No Hindi film has ever been shot here before. We start shooting in 10 days."

Boman Irani (DCP D'Silva/Vardhaan in Don) has been training under Prashant Sawant for two-months now. He has lost quite a bit of weight. "Boman will look completely transformed in Don 2. He's building his muscles too as he has to look tough. He's doing almost two hours of cardio, weights and circuit training with a diet designed by Prashant's wife Maya (also a fitness instructor). Boman's diet is a high-protein one with little carbohydrates and absolutely none after evening with lots of protein shakes," reveals our source.
