SEO KEYWORDS

Hey! We're a small start-up and I'm very new to the world of web dev, so far I understand that keywords are not the be all end all, but they help with targeted searches and rankings. I'm wondering how exact I have to be with with keywords and phrases, for context, we're an online fitness coaching/personal training brand. A high volume search I'm looking to target is geo-targeted landing pages, so phrases like "personal trainers near me" "gyms near me" "Sydney personal trainer". I've created a web-page template headed "Your Fitness Journey in Sydney Starts here" Followed up with "Are you living in Sydney and looking for a personal trainer?" Will google AI view these as similar enough to be showing them to people that search these terms? Or am I going too broad with it? I'm also adding pages for each suburb of my local city to fine-tune the keywords too.
