Kohli is arguably the fittest Indian cricketer and as captain, he expects his teammates to cut no corners on their physical well-being.
At an event here today, Kohli recalled how he started paying more attention to his fitness.
"It was after the IPL in 2012. Till then I did not focus much on the physical aspect. I never got into the minute details of fitness, things like what I need to eat from morning to night, how much I need to work out, how much I need to train. After that IPL, I started listening to my body," said Kohli, whose next challenge is the tour of the West Indies starting next month.
"I made a lifestyle choice (back in 2012). I wanted to explore a new side of my body to take me to the next level because I never wanted to be average. I wanted to best in the world. So I always had that mindset but never had the physical ability (before 2012)."

The level Kohli has taken his fitness to was summed up aptly by India's fitness trainer Shankar Basu. "Virat wants to be the best athlete in the world," he had said recently.
"When you become fit, you feel you can do anything. I will give you one example. I was never a quick fielder. I was never willing to field in every position. But after becoming fitter, lighter and stronger, I overcame all those doubts I had (about fielding). Now it (staying fit, eating right) has become second nature to me," he said.
His world has changed ever since be became a "fitness freak" and Kohli now wants the younger generation of India to pay more attention to health and fitness.
"I have never been as fit as I am today. It has worked beautifully for me. It has become a lifestyle choice for me. Even in off time, I watch what I eat. In fact, I get more excited about fitness, feeling good, being healthy than anything else. That is probably because by body realises that fitness is what I would need after my professional career is done," Kohli added.
