What Exactly is a Thermogenic Pre-Workout?

Pre-workouts are taken before a training session in order to boost your energy and focus to deliver your best performance.

When taken correctly and in the appropriate dosage, they help you workout harder and longer than normal–which over time greatly compounds your results. And who doesn’t want faster results?

Thermogenic pre-workouts differ from standard supplements because they have the added bonus of being designed to also raise your body temperature.

This higher temp speeds up your metabolism via the process of thermogenesis, which sounds like something you learned about in chemistry class.

What Is Thermogenesis & How Does It Boost Fat Loss?

Thermogenesis is the process of generating heat by boosting metabolism. This creates an internal environment in your body that makes it conducive to burning fat.

You know how you tend to eat more food in the winter months?

This is because your body is in overdrive to maintain your body temperature during the cold weather, which is why experiences such as cold showers and ice baths are lauded for their intense thermogenic effects...

Luckily, you can skip those chilly showers since it has been scientifically proven that thermogenesis can be induced effectively by diet alone–which includes pre-workouts!

Popular & Effective Ingredients To Look For

While most regular pre-workouts will contain similar ingredients, the hybrid thermo supplements have additional compounds to look for.

There can be some overlap in which ingredients help give you more energy and which ones are used for thermogenesis, but below we’ve listed the main ones to look for.

So, when you read the label of a so-called thermogenic fat burner, be on the lookout for these main key ingredients to get the results you are looking for:


Our good friend caffeine is found in virtually all pre-workouts, and for good reason.

Caffeine is the most widely consumed stimulant in the world and has several fat loss promoting effects.

It has been shown to boost your metabolic rate and overall fat oxidation. Additionally, caffeine will stimulate the production of adrenaline and increase your aerobic capability and power output.

While caffeine and other stimulants are great when taking in the morning, be careful to avoid too much caffeine later in the afternoon/evening as it will keep you from getting a restful night’s sleep and hamper your recovery.

Green Tea Extract

What is green tea not good for?

You’d have search far and wide to find the answer to that question, but luckily you don’t have to look far to find a fat burner pre-workout containing this compound.

The polyphenol and catechin antioxidants in green tea extract make it a good alternative to coffee-sourced caffeine since they support the health of your nervous system instead of overstimulating it and potentially making you jittery.

Capsaicin / Cayenne

Capsaicin is one of the best-known thermogenic compounds and is the active ingredient which makes red chili peppers so hot. If you’ve ever eaten spicy food and started sweating, you can thank capsaicin for your misery.

Be on the lookout for either “capsaicin” or “cayenne” listed on the ingredients. Note that if your pre-workout supp doesn’t contain capsaicin, you can still get it in your diet in the form of a good hot sauce or salsa.

Just be careful to not overdo it with this fat burning compound as too much capsaicin can give you stomach problems. So it is best to avoid large amounts, especially within 2 hours of bedtime.

Conjugated Linoleic Acid (CLA)

CLA (Conjugated Linoleic Acid) is a fatty acid typically found in animal products such as beef and dairy.

It has been found to target fat deposits, promote muscle tone, and boost metabolism.


L-carnitine is an amino acid that plays a large role in boosting metabolism and energy production.

It does help with fat oxidation by driving fatty acids from the bloodstream to the mitochondria, where they can be used for energy. Also well-known for enhancing mental focus.

How To Maximize Your Results From Thermo Pre-Workouts

When To Take

Like most pre-workout supplements, you’ll want to take it about 30 minutes before your training session.

This is just enough time to start feeling the effects so you can get your pump on, but not too much so that the effects start wearing off.

Also, on rest days you can take it 30 minutes to an hour after waking up to still get the metabolism boosting effects.


Due to the (typically) added caffeine, avoid taking in the late afternoon or evening, especially if you are sensitive to caffeine’s stimulatory effects.

How Much To Take

Exact dosages will vary depending on which product you opt for, but in general you will just need to take 1 serving of the tablet, capsule, or powder.

Cycling Your Dosage

While I would love to tell you that you can and should take a thermogenic fat burner every single day, the reality is that you need to cycle it.

This means using for up to 6-10 weeks in a row before taking a 4-6 week break before using again.

Here's the deal:

The reason is that you want to avoid developing any dependencies or tolerances to any of the ingredients–especially caffeine.

Basically, if you start noticing the effects to be less and less each time you use it, that is a good sign that you should take a break.


Though it is tempting to just up the dosage if you are not getting the full effect, this will only worsen your tolerance and overload your body so please don’t take more than the recommended amount indicated on the package.

Thermogenic Pre-Workout Benefits

So we’ve already touched on how thermogenesis is a natural fat burner, but what else can these pre-workout supplements do?

As a recap, here is a summary of why other gym-goers love them:

  • Boosts metabolism for 24/7 calorie burning
  • Increases focus & energy levels
  • Improves workout performance
  • Suppresses appetite

What Are The Side Effects?

If you read the benefits above thinking “there must be some side effects to these things!” you’d be right.

Here are the common culprits:

  • Lack of sleep / difficulty sleeping
  • Dehydration
  • Jitteriness / anxiety

But luckily, the above unwanted reactions are minimal and easily avoided...

Here’s why:

Caffeine content is the main contributor to the unwanted effects, so they will be greater if you are not accustomed to consuming caffeine. As mentioned earlier, avoid consuming this powerful stimulant later in the day in order to get restful sleep.

On a related note, if you aren’t used to taking caffeine, start by slowly ramping up your dosage up to the recommended amount over a period of 1-2 weeks.

Since thermogenic supps up your core body temperature (not to mention how much harder you will be working out and burning extra calories!), you will naturally sweat more and need to drink more water.

Be sure to drink at least 3-4 liters of water per day to stay hydrated as you don’t want dehydration to hamper your performance and limit your gains!
