Is this typical?

I have a personal trainer who is so so kind. We are both the same age and into very similar things so sessions tend to flow very well and we’ve grown great rapport. The only thing I find is that we only speak during sessions. They never text to check in throughout the week on goal progress or anything. Whenever I meet a new goal (running mile, exceeding goal on the stairmaster, etc.) that I wanted to share with him b/c I’m feeling proud of the progress I’ve made working with him, I am so hesitant. I tend to think “he’s probably doesn’t want you to blow up his phone with this kind of stuff?”. I’ve had other people tell me that their trainers would frequently check in, give tips, etc. outside of their training sessions. Just want to ensure I’m not overthinking this. I just want to get the most out of this experience.
