Why Muscle Spasms ?

Dumb question that I don’t know the answer to. Why do my muscles “twitch” or “spasm” sometimes? What causes this?

I’ve been sick recently and took 2 weeks off training. On Sunday I lifted again and both yesterday and right now my right tricep (or one of them) is “twitching” every now and then. What is this? It doesn’t hurt or anything, I’m just curious.

Possibles:
a. Low water
b. Low potassium
c. Overstressed
d. Neurological

These are my guess. Maybe try a good deep massage to relax it?

Spasms are bad. Pain. Weakness.

Twitch is just a minor thing. Common. It will go away as you train more frequently.

Thanks yasser and skw.
