I am ready to get healthy and build muscles but I've never done any type of working out or healthy eating. My question is if I was to sign up here can you get a personal trainer and do they help you with learning how and what to eat well?

Ask for reggie he's the trainer there

Yes

They have a personal trainer that will recommend exercise regiment if you sign up for classes. They dont discuss diet or food choices

Planet Fitness routinely has people that work there as trainers and have sessions most days of the week to show you how to work certain types of body parts as far as nutrition I don't know never looked into it

Personal trainer yes, i don't know about a meal plan.

Yes and yes
