Here`s Why you Feel Shaky After Workout


Is it Normal to Feel Shaky After Working Out?

You`re probably disturbed about how shaky you get after a vigorous workout. It`s usually nothing to worry about, however, there are times when it`s an indicator of a severe problem. Let`s discuss the various reasons you may feel shaky after working out and ways to prevent it.

Reasons you Get Shaky After a Workout

There are many causes of shaking after exercise, and some of them come with various symptoms. To deal with shaking after a workout, you may need to pay close attention to your pre-workout and workout habits. Here are some things to look out for.

Muscle Fatigue

Muscle fatigue is one of the most common causes of tremors after exercise. When you`re engaged in physical activity, your central nervous system (CNS) fires motor units to contract your muscles. A motor unit consists of a motor neuron and muscle fibers. This firing of motor units provides some force for your muscles. As the workout gets longer, your muscles rapidly alternate between contractions and relaxations, which results in tremors. Your CNS may also lose its ability to forcefully move your muscles. Fatigue then sets in, making you twitch and get shaky. You may also feel some soreness.

At this point, you should know that you have pushed yourself too hard and should reduce the intensity of your exercise. It could also happen if you recently took up a tougher exercise challenge.

Holding a Muscle in One Position

Shaking can happen when you keep a muscle in one position for a long time. This particularly happens while doing planks or a barre workout, due to the activity of motor units. Some of the motor units in your muscles are only required for powerful movements. Holding a muscle in place for a long time may get the motor units activated and result in shaking.

Low Blood Sugar

Because your muscles use glucose for fuel, working out could get the glucose levels depleted, especially if you exercise at a vigorous pace or for an extended period.  Hypoglycemia, commonly known as low blood sugar is usually a common cause of this. Some other symptoms that come with this are:

  • dizziness
  • confusion
  • irritability
  • fatigue
  • hunger
  • weakness
  • fast heartbeat
  • headache


Staying hydrated will help you keep your electrolyte levels balanced. Electrolytes are responsible for controlling the function of your nerves and muscles.

Whenever you do an intense activity such as working out, you sweat a lot and lose water. If you sweat too much and become dehydrated, you may experience muscle twitching and cramps. You may also have some of these symptoms:

  • fatigue
  • thirst
  • dizziness
  • weakness
  • confusion
  • dark urine
  • reduced urination
  • headache

How to Stop Post-Workout Shaking

Drink Water

When you rehydrate, you restore your electrolyte and fluid levels.


Stretching after working out will help loosen your muscles and reduce aches, spasms, and cramps.

Eat a Healthy Meal

You can refuel your muscles by eating a post-workout meal. Consuming carbohydrates, in particular, will help you replenish your glucose stores to repair your muscles.

How to Prevent Post-Workout Shaking

Challenge yourself Gradually

As much as it is important to increase the intensity of your workout, you should do so gradually. Rushing it may cause shaking and injury.

Eat a Pre-Workout Meal

Give your body enough fuel before you start exercising. Consume a pre-workout meal 2 to 3 hours before your workout.

Prepare a Post-Workout Meal in Advance

Preparing a post-workout meal before working out will help you refuel your muscles immediately after you’re done working out. This will help you avoid the shaking that comes from burnout.

Hydrate Before, During, and After Exercise

Limit Caffeine Consumption

Reducing your caffeine intake before exercise will help prevent shaking after your workouts.

Warm-up and Cool Down

Before exercise, you should do some warm-up to prepare your muscles for movement. Take some time to cool down after warming up so you can recover and reduce the likelihood of soreness and fatigue.

When to Get Medical Attention for Post-Work Shaking

As already stated, post-workout shaking isn’t usually a thing to worry about, however, there are cases when sufferers may require medical attention. If you notice any of these symptoms, you should seek medical help immediately:

  • fainting
  • seizures
  • prolonged shaking
  • difficulty breathing
  • dizziness
  • vomiting
