Advice needed: male personal trainer kept wanting to talk to me

There’s a male personal trainer at my gym who keeps bothering me 😑. I’ve never initiated a conversation, always wear headphones, and try my best to avoid him, but he still finds excuses to talk to me and be physically near me somehow. I’ve tried going to the gym at different times of the day, this dude is always there :/

It started with him asking if I was using equipment when there were other machines available. Then, while training a client, he left them to give me unsolicited advice during my pull-ups. Later, he approached me to introduce himself (already knowing my name) and now changes into workout clothes to use machines near me when I’m there.

He even took off his headphones to eavesdrop when I was chatting with another guy about my form, and I’m sure he would’ve interrupted if I hadn’t walked away and ended my session.

I’ve made it clear I don’t want to talk to him—avoiding areas he’s in and ignoring him—but he doesn’t get it. I’ve tried different times of day, and he’s always there. It’s so frustrating, and I’m unsure if I should confront him directly.
