Talwalkaars was doing ok in my town, and then Gold's gym opened, and even people who had paid advances, are now gold's gym members..
As for me, i just have my own equipment, with equipment becoming cheaper and more easily available, many people prefer to get the gadgets and weights home..
things are changing real quick, and just because a concept seems to work in other countries, for example like in the US, it is not necessary that it will work here.
In the US, people earn to enjoy, in india, people earn to save and save and save, although with the new generation, saving is a bit of a lesser issue, but all the same, genes of indians are a bit diff from genes of white people and that must be kept in mind.
