You’re looking for ways to do increase the intensity of your workouts and increase the amount of fat you burn. You hop on the treadmill with your hoodie on in an attempt to burn more calories.

More sweating means more calories and fat burned, right?

Does Working Out With A Sweater Burn More Fat?

You will sweat more which will make you lose water weight. However, this is not the same as losing fat and you will gain it back as soon as you drink fluids. Working out in a hoodie does have some benefits such as warming up your muscles, pumping more blood and nutrients into them, and releasing more toxins through the skin.

Water Weight Loss

If you were to workout or do cardio in a sweater, you would notice that you lost weight if you hopped on the scale right after. Perfect, what an easy hack to lose fat, right?

Not quite, the majority of this weight is going to be water weight. Since the body’s internal temperature will rise, the sweat glands will trigger and cause you to sweat in an attempt too cool the body.

You are sweating out all the fluids that you drank during that day. You will weigh less but it’ll be from the increased amount of fluid loss, rather than the body actually instantly losing fat.

This water weight that was lost after exercising will be gained back once your drink more fluids to replace the lost ones.

A safer way to lose more fat is to run for longer periods of time and to eat less. If you’re looking for supplements that help with weight loss, see here.

Fat cannot be instantly burned and takes a lot of consistent exercise to lose. A calorie deficit is also required for the body to burn fat. That is, eating fewer calories than your body is burning.

How long would it actually take to lose fat? Well, a pound of fat is equal to 3500 calories. To safely lose weight without harming yourself you could eat in a deficit of about 500 calories per day. If your maintenance calories were 2600, you would want to eat 2100 calories every day.

This would mean that in 7 days, you would be in a 3500 calorie deficit equal to one pound of fat. You just lost a pound of fat in a week. This is quite fast and reasonable. Eating any less is not safe for the body.

This would equal in losing 4 pounds of fat per month. So you can see that it is not possible to instantly lose a couple pounds of fat from once intense treadmill workout wearing a sweatshirt.

Don’t forget about cardio! If you are burning 200 calories per day from your cardio, this puts you in a further deficit and will burn fat even faster.

Staying hydrated is a great way to help burn fat. Without water, the body can’t properly metabolize the stored fats or carbs. This means that fat will be stored in your body, rather than being burned.

The process of hydrolysis occurs when water molecules in your body react with fats to create glycerol and fatty acids. So, drinking more water leads to more fat being burned.

Studies have also proven that people who drink more water burn more calories as it increases the body’s resting energy expenditure.

Sweating More Doesn’t Equal More Fat Loss

Let’s consider the Thermogenic Effect. Thermogensis is the dissipation of energy through the production of heat. The more calories that you burn, the hotter you get. However, getting hotter does not result in more calories being burned.

Sweating will only cause you to lose water weight that is put back on once your drink fluids. This weight loss will not be fat loss.

Fat loss can only be accomplished by eating fewer calories than your body burns over a period and there is no such thing as instant fat loss. It takes time for your body to burn off fat.

This tactic of sweating off as much water weight as possible is used in sports such as boxing where the athlete has to make a weight class. By wearing a hoodie for their workout they could burn off a lot of extra water weight.

They could potentially lose 5 lbs doing so to reach their desired weight class. Then, once fluids are consumed they would gain the 5 lbs back.

Why do some people sweat more than others? This all depends on weight, genetics, age, and fitness level. I’m sure you’ve seen a huge guy at the gym soaked in sweat.

This is because they have more body mass and generate more heat. It also takes more sweat to cool off a large surface area.

As we age, our bodies lose their ability to cool themselves as effectively. Muscle mass also produces more heat than body fat does, so those with a lot of muscle will tend to sweat more.

If your fitness level isn’t that advanced and you do an intense workout that your body isn’t used to, you can expect to sweat quite a lot.

Spicy foods may also make some people sweat since they increase the body’s internal temperature

Benefits Of Wearing A Hoodie While Exercising

First of all, the body does burn more calories in hot weather rather than cold. This is because the heart has to work harder to prevent the body from overheating. Over 70 percent of energy produced by the muscles during exercise is lost as heat.

Harder exercise leads to your heart pumping more blood and nutrients to your muscles. While also pumping to the skin so that heat can escape.

In cold weather, your heart is mainly only pumping blood to the muscles, as it does not need to escape through the skin.

Sweaters are a great way to warm up at the beginning of your workout. If you’ve heard of guys wearing a pump cover for the first few exercises of their workout, this is what they’re doing.

This will help warm up your muscles and joints, helping increase mobility and reduce risk of injury. It’s also good for release of toxins through sweat. If you are someone who doesn’t sweat very easily, then starting off in a hoodie is a great idea.

However, if you’re of those guys who are soaked the entire workout, you can probably skip the hoodie and start in your tank top.

Being warm will force the blood to pump more blood and nutrients into the muscles, increasing your pump, insulin sensitivity and endurance levels.

If you’re wearing a super comfy sweater, it can make training a lot more favorable. Note that you will want to wear a hoodie that is made of moisture wicking fabric so that the sweat can evaporate. If not, you will be left with heavy, wet clothes that feel gross.

Sweating also has some benefits such as healthier skin. By exercising hard, your body is circulating more blood, which allows more oxygen and nutrients to reach the skin cells. It will also flush toxins out through your skin.


Working out while wearing extra layers can mess with your bodies natural cooling system, which can actually make the exercise feel harder.

You also risk dehydration. The more fluids you sweat out, the more dehydrated you can become. If you lose a lot, this can lead to dizziness, fatigue and headaches which can be very dangerous while training.

Make sure the hoodie is not too tight, restricting mobility or range of motion, one of the most important parts of building muscle. If you can’t stretch the muscle fully because of your hoodie, do not wear it while training.

The hoodie can make you so hot and sweaty that you are unable to finish your workout. If that is the case, ditching it may allow you to perform a few extra exercises or run for another 10 minutes.


Working out in a sweater will not burn more fat than working out without one.

It will help you get your muscles warmed up and prepared for your heavy sets. This can possibly help prevent injury.

If you like working out in a sweater, then do it. If it makes you too sweaty and uncormfortable, then don’t!

Drink plenty of water if wearing a sweater! This will prevent you from becoming dehydrated and possibly injuring yourself or passing out.
