33F - want to get fit so I can be independent when I’m 70+

I’m trying to get back into exercising. I used to run a lot and not strength train, which led to a lot of injuries that knocked me out for years. Now I’m trying to start again.

I’m at a healthy body weight but could do with loosing fat and building muscle.

What is a good weekly split? I don’t particularly like the gym or strength training, but realise it’s important. I do like running but right now 5km is the most I can do.

Is running 3 times a week and strength training 2 times a good split? Is it enough?

What strengthening exercises should I be doing? I’m so lost at the gym.

Thanks!
