Talwalkers gym is no doubt one of the best gym in India with more than 25000+ members and they also have a very good equipment and almost everything you need to get in shape and get fit, healthy and get the body you want. I don't have any issues over there.
But all that equipment and resources are of no use if you just can't simply utilize them properly and you gym trainer is not even little but free to help you out with minor of the problems. I also had an incident like that as I went there to lose weight and get slim but the trainers were not helpful at all.
I know you need to do training by yourself and not everytime a gym trainer will be with you but even sometimes you are not familiar with the equipment they won't help you or just show attitude or mostly in their phone all the time its just really get frustrating when its something like that and you can't really concentrate on workout when someone is being rude with you and you just don't want to go to the gym as you know someone will ruin it for you and waste the money you already paid and that what experience I had. I don't know what experience other people had but it was ridiculous for me.
