Sourav Ganguly recently revealed the India Test skipper Virat Kohli had hit the gym right after batting for more than six hours, in order to scale bigger heights with the bat.

That Virat Kohli is in the form of a lifetime is no secret. The India Test skipper has already racked 640 runs in the ongoing five-Test series against England, and is nearly 250 runs ahead of the nearest competitor. With two centuries, including a breathtaking 235 in his latest venture with the bat, he has been an unstoppable force in the four Tests so far, and Chennai is hardly expected to be any different.

The Delhi lad's fitness has been something of a legend, with Kohli setting new benchmarks when it comes to physical strength and endurance. During his extraordinary run in the 10th edition of the Indian Premier League (IPL) earlier this year, he revealed the secret to his remarkable fitness — which included a 100 squats to strengthen his lower body that contributed to his fantastic running between the wickets.

Former India captain Sourav Ganguly revealed another interesting tale that speaks volumes of Kohli's dedication towards his fitness as well as to the sport. On ESPNCricinfo's Match Day, the cricketer-turned-commentator narrated how a friend of his saw Kohli hit the gymnasium with a trainer straight after batting for nearly six hours and batting past the 150-run mark.

When Ganguly's source asked Kohli the reason for heading to the gym after such a gruelling innings, the latter revealed that he "wanted to work out at that moment because he was tired, and that was the only way he was going to get double and triple hundreds in Test matches."

Kohli's innings however, ended at the 167-run mark (after facing 267 deliveries and batting for nearly seven hours), with the Indian skipper sharing a vital stand with Cheteshwar Pujara for the third wicket and establishing the platform for a commanding first innings total.

Kohli continued his silky touch with the bat in the next two matches in Mohali and Mumbai respectively, scoring a half-century at Mohali before notching up his career-best at the Wankhede Stadium in the fourth Test.

In Mumbai, Kohli, along with Jayant Yadav's gritty 104, helped the Indians overshadow England's first innings total of 400 by 231 runs. Ravichandran Ashwin and Ravindra Jadeja did the rest, as England were skittled out for a meagre 195 to collapse to an innings and 36-run loss, surrendering the series 0-3. The Indian captain was adjudged Man of the Match for his performance in Mumbai and will be heading into the final match in Chennai brimming with confidence.
