Stallone and Akshay had worked together in 2009 movie "Kambakkht Ishq". It was then that the former was introduced to the 'bhurji' and its benefits, said a statement from PVR Pictures.
Akshay enlightened Stallone about benefits of ‘chaach' or ‘buttermilk' as it's low on fat and easier to digest.
On the sets of "Escape Plan", Stallone advised Schwarzenegger to try the combo for himself to see the difference and advised him to make it a part of his routine, said a source from PVR Pictures, distributor of the film in India.
The "Terminator" actor was also advised by Stallone do yoga. Directed by Mikael Hafstrom, "Escape Plan" will release here Oct 18.
