The two actors along with Kay Kay Menon, Sharad Kapoor and Krushna Abhishek are shooting in Hyderabad for David Dhawan's comedy thriller "Hook Ya Crook".
"Shreyas is going to be on a fitness regime for two weeks while he's doing a marathon shoot of 'Hook Ya Crook'," said a press release.
"John (Abraham) has set up a gym at the hotel they are staying at and has persuaded Shreyas, along with Kay Kay, Sharad and Krushna to sweat it out every evening after pack up. Also, Shreyas would be on a stringent dietary regime chalked out by John; so that means keeping a check on what he eats and when," added the release.
