Tremor/fasics

35 yr old male, recent history of presumed benign fasciculation syndrome, and cervical radiculopathy as seen on mri and prior emgs;

When my arms are in extension i feel mild tremor/fasciculation in my triceps on both sides. No weakness. What is that? I have had a emg study recently (showed cervical radiculopathy) for other reasons and tricep muscle were both normal. I did do a new exercise some days ago with seated cable rows and pulling back motion so not sure if related but i have felt this before that workout too albeit less.

Its like the type of tremor/shake or fasic when you work out and your muscle shakes a bit but way less.
