Of late, a number of star kids - Ranbir Kapoor, Varun Dhawan and Arjun Kapoor, among others - have been in the news for their fitness routines. Joining this league is another star kid - Aamir Khan's son Junaid (right) - who has been on a training programme for nearly seven months now.It's not clear whether Junaid is being prepared for a grand launch, but he is surely sweating it out with trainers Samir Jaura and Jai Shekhawat. Samir trained actor Farhan Akhtar for his role in Bhaag Milkha Bhaag, and has been working with the actor for 11 years now. "It was Aamir who asked Farhan for Samir's number. Junaid called him expressing his desire to train under him. He was fit already, so the trainers have put him on a general fitness and toning regimen. His physique is leaner now," says an industry insider.
