Why do my muscles twitch?

A day after my work out, I find that my muscles sometimes twitch and spasm (there is no pain) for a few seconds. This is especially true of my pectorals and forearm muscles when I have a big yawn or stretch.

Is that normal? Why does it happen?

    The muscle twitches, aka Benign Fasciculations that may occur after exercise are surprisingly common. After the muscles have undergone an intense workout, biochemical changes take place as the muscle responds to the stress of exercise. Lactic acid builds up in the fatigued muscle and formation of free radicals occur which believe can alter the excitability of muscle tissue. Endurance athletes and runners are particularly prone to the type of free radical formation that can lead to muscle twitches after exercise. Eating more antioxidant rich foods may help to reduce exercise related muscle twitches, although there are no studies to document this.

    To reduce the chance of post-exercise twitching, warm up before working

    out, gradually increase your workload, drink plenty of fluids, and

    incorporate stretching and keep muscles warm.

    Muscles need adequate energy for proper contraction and relaxation, and

    a specific balance of electrolytes (such as sodium, potassium, calcium

    and magnesium) to regulate electrical signals governing contraction of

    the muscles. If either of these needs aren’t met, you may get a

    cramp or twitch.
