Twitchy muscles?

Options
I noticed the last few days that my bicep is twitching randomly. I thought it was dehydration, but I have been focusing on more water including electrolytes and it’s still happening. I strength train 2-3 times per week and have remained consistent for some time, so I don’t think it’s related to workouts.

It’s not overly bothersome, just curious if anyone else has had this happen?
