26.9% percentage body fat. How to train as a skinny-fat woman?

As per title! My visceral fat is 5 which is healthy, but that PBF scares me abit so sending an SOS here.

How should I train to reduce PBF and increase muscle mass? I currently gym once a week till exhaustion (like a 45 min solid all parts body workout), dance 2 hours a week and run once every 2 weeks.

An important note is I don't have a great or huge appetite so I do probably under-eat and not get enough protein for sure haha. I love vegetables and celery juice 🫠
