Muscle Spasms

[Matthew]

Hey guys, after riding today while i was sitting down not doing anything, i noticed that my right bicep was twitching for no reason, and it lasted for about an hour on and off before stopping completely.

Does anyone have any idea whats causing this, and if theres any need to, or way to stop it?

Mine also does this from time to time.

But I always just do something to get my mind off of it and it goes away by itself. Its nothing to worry about, just over working of the muscles or a number of things can cause the spasms.
