I am 27 and I have no hobbies

First off plenty of 27 year olds don’t have any hobbies of note.

I think you need to work out what you want from a hobbie. You say you want something just for you but you have tried reading and the gym and it’s not for you. That’s absolutely fine.

What do you spend your free time doing that you enjoy? If it’s watching films or too much You Tube or frequent trips to the pub you could reframe that as a hobbie in your own mind. There’s nothing wrong with any of that.

Or if you feel like you want a bit more out of your free time than what you are already doing you might need to explore what it is you crave. There’s a million things you could do and you are best places to know what you’d like. You might need to try a few things before you hit on something that really gets you. Good luck.

If climbing interests you, have a look at whether your local climbing gym offers a bouldering induction session or an intro to rope climbing course or something like that. Then they usually have social climbing groups specifically for women which is a great way of making friends and staying interested.

Lots of clubs or groups will have taster or open days so you can try something out and see if you're interested in it. Even the Warhammer stores will let you have a go at painting a model for free to try to get you hooked.

What did you like most at school, or as a kid?

Is there any part of your job that you quite like that you might make into a hobby?

Maybe hobbies aren't for you and you'd find some sort of volunteering more rewarding?

The world is your oyster!

Don't feel down, you have so many opportunities.

I think going to a class is the way to go. It's regular, you don't have to be somewhere on your own trying to have fun, and you learn a new skill.

Try a few different classes, not just one, to see what you like. If you start one, it's easy to start a martial arts class decide you don't like it, quit and then feel and as you still have no hobbies, whereas if you try a few different things, like martial arts classes, art, music, learn a language, do a craft class, that sort of thing, then you can drop most of them and keep only one or two if you really like them and potentially find something you actually enjoy.

I was the same and I’m 37! Takes a while to find something you like.
I do gym classes rather than the gym and I love them. I read. Find a good Netflix box set. I did join a choir but didn’t click with anyone!
I want some more hobbies and think I’m going to start growing veg indoors over the autumn. Also want to paint our bedroom… feel like I’m not capable but how hard can it be?!

Have a look for local choirs and drop in to visit their rehearsals - it's a great hobby :-)
