MUMBAI: Bollywood’s young gun and uber lean young superstar Ranbir Kapoor is all set to don a new look for Abhinav Kashyap’s ‘Besharam’. The handsome actor will reportedly sport a muscly, beefed up look for his next.

Spotted shooting for an ad in Mumbai, Ranbir’s size didn’t betray the extra arduous training he has been undergoing to get ripped and muscular for ‘Besharam’. He was seen in a black tee, faded blue jeans and a tan leather jacket, as he navigated his way to the sets to shoot the ad film.

His trainer Pradeep Bhatia of Elixir Fitness, Andheri had said earlier, “He will need to put on some muscle as he will be shooting quite a few fighting sequences.”

Describing his fitness regime, Pradeep added, “Three days a week we work on his chest, back, triceps, shoulders and legs. Every fourth day, we have been doing TRX suspension training, which is a high-intensity functional workout. I make him run with a truck tire tied to him. Through the week, we also concentrate on a lot of free weight training and 10 sets of push-ups and squats. On the seventh day, he usually takes a break.”

Ranbir is also rationing out his time between his current work commitments (post production work on Ayan Mukherjee’s ‘Yeh Jawaani Hai Deewani’) and his personal life. Reportedly, Katrina Kaif was next door shooting for a film while Ranbir was shooting for the ad, and she dropped in to pay him a quick visit on sets.
