Dehydration is a common practice among bodybuilders before competitions, as it is believed to improve the visibility of their muscles and increase vascularity. Bodybuilders may manipulate their water intake during 'peak week, the week leading up to a competition, by increasing their water consumption and then drastically reducing it in the final 12-24 hours. This practice aims to reduce water retention between the muscles and skin, giving the appearance of fuller and more defined muscles. However, dehydration can have detrimental effects, including muscle cramps, loss of muscle volume, and increased risk of muscle damage. It is important to note that dehydration should not be attempted without professional guidance due to potential health risks.

Dehydration to increase muscle definition
Dehydration to increase muscle visibility is a practice that has been observed in bodybuilding. The idea is that by reducing water retention, muscles will appear flatter and more defined.
The human body is made up of about 50-75% water, with muscles containing 70-80% water. When cells lose water, they lose volume, and this reduction in muscle cell volume can make muscles appear smaller and more defined. However, it is important to note that dehydration can have negative effects on the body and should be approached with caution.
To achieve dehydration, bodybuilders may reduce fluid intake and use prescription diuretics to eliminate water retention. They may also manipulate their sodium intake, as consuming more sodium than usual can cause the body to retain water. However, this water retention is only temporary and will be eliminated within 24-36 hours.
Dehydration can have several detrimental effects on the body, including muscle cramps, dizziness, headaches, and nausea. It can also lead to a decrease in blood flow to the muscles, causing them to tighten and potentially increasing the risk of muscle damage. In addition, dehydration can negatively impact workout performance, causing fatigue and reducing physical capacity. Therefore, while dehydration may provide a temporary increase in muscle definition, it is not recommended due to the potential health risks involved.
It is important to prioritize hydration, especially during exercise, to maintain muscle health and avoid the negative consequences of dehydration. Drinking plain water before, during, and after a workout is the best way to stay hydrated and minimize muscle tightness.

Water intake manipulation
The practice involves dramatically increasing water intake for a day or two, consuming up to 10-12 liters of water daily. This is done to ensure the body is "flushed" and well-hydrated, with water stored both inside and outside muscle cells. Subsequently, during the final 12-24 hours before the competition, bodybuilders drastically reduce their water intake or cut it out entirely. This reduction in water intake forces the body to draw water from other areas, such as the skin and organs, to replenish the muscles. As a result, the skin appears thinner, and the muscles look fuller and more defined.
However, it is crucial to note that this practice can be risky and may lead to uncomfortable side effects. Horia, a bodybuilder from Romania, shared his experience of consuming only two liters of water total over four days, gradually reducing his intake each day, and abstaining from water on the competition day. He reported feeling uncomfortable, experiencing high blood pressure, and having difficulty sleeping.
Additionally, dehydration can lead to painful muscle cramps and a decrease in athletic performance. It is essential to be mindful of the potential health risks and not to overdo the dehydration, as it can negatively impact the body and may even be dangerous.

Diuretic use
Diuretics, also known as water pills, are medications that increase urination by making your kidneys put extra salt and water into your urine. This is how diuretics clear extra fluid out of your body and bring down your blood pressure. Diuretics are often used to treat medical issues such as heart failure, high blood pressure, or swelling (edema).
When taking diuretics, it is important to monitor your body's fluid levels, as diuretics can lead to dehydration if you don't drink enough water. Dehydration occurs when you lose more fluids than you take in, and it can be dangerous if left untreated. Signs of dehydration include muscle cramps, heat intolerance or chills, constipation, and dark-colored urine.
To prevent dehydration while taking diuretics, it is crucial to increase your water intake and ensure you are consuming enough fluids. You may also need to take electrolyte supplements, as diuretics can cause electrolyte loss, which can lead to muscle weakness, spasms, and cramps.
Some people, such as bodybuilders, may intentionally use diuretics to dehydrate their muscles for aesthetic reasons. This practice, known as "peak week," involves taking diuretics and limiting water intake to reduce the water between the muscles and skin, which can enhance muscle definition. However, it is important to note that this practice can be dangerous and should only be done under professional supervision.

Dehydration and muscle tightness
The loss of water content in muscles can be due to a combination of excessive sweating and inadequate fluid intake, particularly after an intense workout. Certain medications, such as diuretics, antihistamines, and blood pressure pills, can also contribute to dehydration. Additionally, consuming foods with high sodium content, MSG, or substances that you may be allergic to can lead to temporary water retention, further impacting muscle hydration.
The effects of dehydration on muscle tightness can be significant. Mild to moderate dehydration can lead to muscle tightness, cramps, and pain. In more severe cases, dehydration can cause a condition called hypovolemic shock, characterized by dangerously low blood volume, which puts individuals at risk of heart and kidney problems and, in extreme cases, death. Dehydration can also lead to a lack of joint lubrication, resulting in achy and painful joints.
To prevent and alleviate muscle tightness due to dehydration, it is crucial to maintain proper hydration by drinking plain water before, during, and after workouts. It is also essential to ensure adequate sodium, potassium, and electrolyte intake, as these play a vital role in maintaining fluid balance and muscle function. Eating a balanced diet, stretching, and regular exercise can also help prevent muscle stiffness.

Dehydration and muscle cramps
Dehydration occurs when your body loses more fluids and electrolytes than it takes in. Your muscles are 73% water, so dehydration will naturally affect them. When dehydrated, the body prioritises sending fluids and electrolytes to vital organs like the heart and lungs, drawing water from the muscles. This loss of water from the muscles can cause them to tighten and cramp. Dehydration can also affect the transmission of nerve impulses to the muscles, causing cramps.
Muscle cramps are a common occurrence after intense exercise, especially if you have been sweating a lot and not drinking enough water. They can also occur 24 to 48 hours after a workout, so it's important to stay hydrated before, during, and after exercise. Drinking water is the best way to stay hydrated, and you should aim for at least 8-10 cups of water per day, more if you are active or in a hot climate.
In addition to water, you can also consume foods and beverages rich in electrolytes like potassium, magnesium, and sodium to maintain proper electrolyte balance. Good sources of electrolytes include bananas, oranges, nuts, and sports drinks (for intense workouts).
Stretching can also help to ease muscle cramps, particularly calf cramps, which are common in the lower legs. Try these stretches:
- Stand with the toes and balls of the feet on a step, letting the heels hang over the edge. Slowly lower yourself down and hold until the muscle relaxes.
- Stand a few feet from a wall and press your palms against the wall at shoulder height. Slowly bend your elbows while keeping your heels on the floor until you feel the stretch in the backs of your legs.
- Using a chair for balance, stand with one leg extended behind you. Keep the toes planted and the heel raised while pushing the back foot towards a wall behind you. Repeat on the other side.

Frequently asked questions
Bodybuilders dehydrate their bodies to reduce the water between their muscles and skin. This makes their muscles appear bigger and fuller, and their skin thinner.
Bodybuilders manipulate their water intake in the days leading up to a competition. They increase their water intake to anywhere between 10-12 litres a day for a few days and then dramatically cut down their water intake 12-24 hours before the competition.
Dehydration can lead to painful muscle cramps, loss of muscle volume, and increased risk of muscle damage. It can also cause a loss of skin volume, making the skin look leathery, drier, older, and less elastic.
Bodybuilders can focus on maintaining a balanced diet with adequate sodium, potassium, and other electrolytes. They can also increase their water intake for just one day before a show to ensure the body is 'flushed' and not dehydrated.
