Help! Do they have Bootcamp In Mumbai?

Hi Guys seen heaps of great posts on places to wine and dine along with places to visit which is making me a well rounded individual. As such I am seeking places in Mumbai which host Bootcamp style fitness training outdoors to lose some of the hospitality which has accumulated around my waistline.

I am hoping there are some fitness enthusiast out there who knows where they are held or know of groups who participate in that style of training.
