Cricket coach Balvinder Singh Sandhu and team on the physical prep that the cast of Ranveer Singh's sports film is undergoing

In the midst of a merciful break that had punctuated their practice session, cast members of Kabir Khan's '83 were summoned by coach Balvinder Singh Sandhu to witness what a ball, hurled at 90 miles per hour, looked like. "I set the bowling machine at the speed and got them to see what that pace looked like. Watching the balls being shot like bullets, they were taken aback. Those were the balls that we [1983 cricket team] faced. They realised the [importance] of portraying people who played to that pace, and were then further determined to up their [act]," says the former cricketer, who has been mentoring the cast for eight months.
Whipping Singh into shape
Then fresh off the shoot of his cop drama, Simmba, leading man Ranveer Singh was way too muscular and heavy to play the quick-footed Kapil Dev. At about 12 kilos more than desired, he had to shed the extra weight, up his lean muscle mass and stamina, and simultaneously participate in sports-specific training that cricket demanded. "When a bowler jumps and lands, there's a back-foot and front-foot impact. To bowl like Kapil, he needed strong legs. We started working on his glute muscles, along with isolated leg-strengthening exercises," says Sandhu, as fitness trainer Rajiv Mehra adds that glute strength plays a vital role in preventing injuries. "When the glutes fire during bowling, the muscles around the hips and knees don't take the load. This helps us keep them injury-free," he says.
