"Nargis recently visited a Muay Thai boot camp for 12 days in Phuket to learn the core of the form. Known for her astute sense of fitness, this is something she absolutely wanted to do and since she found a little breather in her schedule amidst busy schedule," a source close to Nargis told IANS.
"Nargis disconnected completely from everyone for those 12 days to focus on getting the essence completely," the source said.
The source added that this preparation might be for one of her upcoming Bollywood projects, which will be announced soon.
In her international debut film "Spy", Nargis is said to have an action sequence.
