I was at Talwalkar there is a general trainer who is OK kind of trainer, if you want to know proper technique you have to go for PT personal Trainer which is costly nt for middle class ppl.
Good things you can have steam bath no limit , equipments are good, only few trademill where not working, overall good less crowded if you can pay good money it’s good for you I had paid 14k something yearly at koperkhairne but I was not satisfied bcoz we have to pay monthly for gym trainer, you should include that in yearly subscriptions so that you will get more business that’s it.
