Started gym finally! Is PT really worth it?

I(28F) listened to you girls and started gym yesterday. It's a local gym closeby, and I have also got a PT and it costed like 8k. So it's a total of 9.5k for me.

I am lean and didn't care about fitness ever, since I am turning 29 soon, I wanted to build a routine I can stick to. Yesterday felt good, every part of my body is aching.

I wanted to know what more to expect. I am also wondering if it was worth it to pay and 8k for PT. Does it really help? And anything more you girls wanna tell me about workout, diets, anything.

And pre workout meal ideas.
