Looking for a Gym Buddy & Gym Suggestions

Hi everyone! I’m a beginner looking to start my fitness journey. My goal is primarily to gain weight/muscle.

I’m a bit anxious about going alone as I’ve never stepped into a gym before and I'm worried about the environment/crowd. I’m looking for a gym near Manasagangothri or Jayalakshmipuram that is female-friendly and affordable.

A few questions:

1. Are there any other girls in this area who would like to join me? Having a gym buddy would really help with the anxiety!
2. As a complete beginner, is a personal trainer for the first month worth the cost? How much should I expect to pay in Mysuru?
3. Do any gyms in this area have specific female only hours?
4. For the girls here who have successfully gained weight/muscle, how was your experience? Any tips for a vegetarian?
5. Do any gyms offer weekend-only or 3-day-a-week memberships?

Thanks in advance!
