Does Working Out Make You Poop?

You’ve probably heard the saying, “You are what you eat.” But what you eat can also have an impact on how frequently you… shall we say… relieve yourself.


It’s no surprise that exercise has a range of health benefits, but it can also have an effect on our bowel movements. In fact, exercising regularly is often linked to having more regular and healthy bowel movements. But why is this? While there is still more to be discovered, scientists believe that physical activity involves neural pathways and hormones produced during activity that incredibly affect the digestion process.

The body needs to direct energy into both working out and digesting food. So when the body receives cues that it needs to dedicate more energy to exercising, such as when you’ve just completed a hard interval session or lifted weights at the gym, your brain will divert energy away from digestion — meaning digestion slows down. This can lead to temporary changes in intestinal patterns or difficulty pooping on certain days.

What Causes Pooping During Workouts?

Working out can lead to some pretty unpleasant mid-workout surprises such as pooping. Although it’s not a pleasant experience, it can be a sign of a healthy gut. There are a variety of reasons why you may experience pooping during a workout, so let’s take a closer look at what causes it.

Intense Physical Activity

While it may be uncomfortable, pooping during a workout or shortly after is surprisingly common. This phenomenon is usually due to intense physical activity, which can cause increased intestinal motility. Intestinal motility refers to the process by which your intestines move food through your digestive system. When you exercise, your body diverts blood flow away from your intestines and toward your muscles, leaving less blood available for digestion and thus slowing the process down. This causes feces to build up in the intestines, leading to cramping and discomfort that can make you need to poo during a workout. In some cases, this extra blood flow can cause peristalsis – the automatic contraction of muscles that propels food through the last part of the digestive system – resulting in an urgent need for a bathroom break

Other factors might contribute to this phenomenon as well; dehydration or drinking too much water before exercising can affect digestion and cause diarrhea. Additionally, certain diets such as low-carb or high-fiber diets may increase intestinal motility while exercising, leading to pooping during a workout. Finally, medications like laxatives or antibiotics may also contribute to bowel movements soon after exercise (or even during). Overall, when all of these factors are combined with intense physical activity it’s likely that you’ll experience an urge to use the restroom while working out.

Changes in Diet

Changes in diet can be a major contributor to pooping during or after exercise. Eating foods high in fiber, particularly right before engaging in exercise, can result in the need to go the bathroom. High-fiber foods take longer to digest, shifting much of the digestive process into your workout. Foods like beans, lentils, broccoli and legumes will give you that bloated feeling that makes it hard to concentrate on your workout.

Additionally, many people opt for an energy gel or sports drink before a workout. Drinks high in sugar and carbohydrates can draw water into the small intestine and “lubricate” its contents causing you to have an increased urge to bowel movements. If you plan on having an energy drink or gel right before exercising—make sure to use the restroom first as it might be too late afterwards!


The act of working out can be a stressful experience for the body, leading to an increased production of stress hormones such as adrenaline and cortisol. During moments of stress, these hormones can increase the person’s heart rate and cause blood vessels to dilate. The dilation of blood vessels leads to decreased absorption in the intestines, resulting in softer stools that are easier to pass. Additionally, when someone exercises their abdominal muscles and rectum are contracted repeatedly which can lead to increased bowel movements and necessary pooping during workouts.

How to Prevent Pooping During Workouts

Pooping during workout sessions has become a common occurrence for many gym-goers. While this can be embarrassing, it shouldn’t stop you from getting the most out of your workout. Fortunately, there are a few simple steps that can be taken to prevent this from happening. In this article, we will explore these strategies and discuss how to prevent pooping during workouts.

Eat Slowly

When it comes to preventing pooping during workouts, eating slowly and not overeating prior to exercise can be an effective strategy. Eating quickly can cause a feeling of fullness before you have had time to truly register the amount of food you have eaten, resulting in excess intake. This can lead to bloating and discomfort during exercise. Eating more slowly allows your body time to process the food and helps prevent overeating, making it easier for your stomach to handle exercise.

Additionally, eating a smaller meal or snack prior to exercising that is higher in carbohydrates than fat or protein can help keep digestion lighter for a workout session. Eating foods with a low glycemic index like whole grain breads and cereal, as well as fruits like apples and pears will help prevent stomach upset as you move.

It’s also important to stay hydrated prior to exercising by drinking plenty of fluids throughout the day; because dehydration can add to discomfort during exercise leading to digestive issues and even cramping, avoiding dehydration will help keep your stomach settle during workouts.

Drink Water

Drinking plenty of water is an effective strategy for reducing the risk of pooping during exercise. Without adequate hydration, your body may not have the ability to naturally regulate its digestive system. Water helps to dissolve solid waste and move it through the intestines quickly and efficiently.

Before starting any exercise, make sure you are properly hydrated. It is best to drink between 16-32 ounces of water about 2-3 hours prior to beginning your workout. If you are exercising for more than an hour, aim to drink 8 ounces of water every 15 minutes during your session. Additionally, consider drinking a carbohydrate beverage with electrolytes if you’re going to be exerting yourself beyond 90 minutes. Studies have found that this can reduce feelings of pooping due to dehydration or creating lactic acid build up in your body..

Avoid High-Fiber Foods

Eating high-fiber foods shortly before a workout can trigger pooping. Fiber is essential for digestive health, but too much fiber right before a workout can spell trouble, especially if you’re doing high intensity exercise. Because fiber slows digestion and absorption in the body, it turns into a fuel source that produces more gas and causes intestinal discomfort when paired with physical activity. To prevent this from happening, be sure to avoid all high-fiber foods within an hour of exercising.

If you do plan on eating foods with high dietary fiber—such as berries, vegetables, oats and legumes—make sure you enjoy them several hours before your workout as opposed to right before getting active. By doing this, you should have enough time for digestion and will reduce the likelihood of having an unexpected bathroom break during your exercise routine.


The answer to the question, “Does working out make you poop?” is probably yes, depending on several factors. During a workout, your body increases its core temperature and blood flow to the large intestine, which can have both positive and negative effects. In some cases, physical activity may be beneficial for your digestive system and can help to alleviate constipation. However, it may also give you an urgent need to use the restroom due to the effects of exercise on hormones and muscle contractions in your GI tract. Therefore, it is important to consult with a health care provider if you are experiencing excessive bowel movements or other symptoms that may be related to exercise-induced constipation or diarrhea.
