Is there a specific reason why you shouldn't exercise immediately after getting Botox?

I thought Botox was simple, but...
When I actually looked into it, I found that there were more things to be careful about after the procedure than I thought.

I have a lifestyle where I go straight to the gym after work.
If I have to skip exercising on the day of the procedure, I think I'll have to reschedule. 🥲

I only need to avoid it for a few hours.
Or I'm wondering if it would be good to take a day off.

For those of you who actually went about your daily lives after getting Botox, was it okay? 😊
