India captain Virat Kohli and head coach Ravi Shastri have mandated the fitness test.
"Every team management should have freedom to make its own decisions," Ganguly told Hindustan Times. "If Virat Kohli, Ravi Shastri and the trainers feel that’s the way, so be it. We don’t need to poke our noses all the time. If they demand, the captain of the India team and trainers demand that we need to be at this (fitness) level, so be it."

There were reports that the same yo-yo test passing rule, which has ensured Men in Blue scale further heights when it comes to the international fitness standards, isn't being followed at the "A" level, that works directly as a feeder system of players to the national side.
"If you want to do it with the senior team, might as well do it when you are young (on the fringes). It makes it a lot easier," Ganguly added.
The former India skipper has a lot of trust on Kohli and Shastri as the team builds towards the next year's T20 World Cup in Australia.
"I am sure Virat is putting all his efforts towards that," he said. "Ultimately, the players have to play. We are putting good systems in place. The players have to win and they have the team to win."
"But T20 cricket demands freedom to play freely without worrying about your place in the side."
"We as people, who are working behind the scenes, will try and create systems so that they can play without having to worry about anything else," Ganguly added.
