Muscle Twitching

[bigaspirations]

A friend of mine tells me that his shoulder muscles were twitching right after a shoulder workout, and that this is a good thing. Is this true? Are these muscle spasms or something else?

I hear that muscle twitching can be a symptom of overtraining.
Not sure how much truth there is in it.

Anyone else?

Obviously that doesn't mean everytime a muscle twitches its being overtrained.

Muscle twitching is simply hyper-excitability of the individual motor units within a muscle, unlike what happens with a fulland contstant contraction of a cramp. It generally shows up when the muscle is stressed heavily or used in prolonged activity, beyond it's normal scope. It's not an indicator of overtraining per se and is relatively inocuous.
