What Exactly is a Thermogenic Pre Workout?

Pre workouts for fat burning 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 servings, they help you workout harder and longer than normal – which, over time greatly compounds the outcome. And who doesn’t want faster outcome?

Thermogenic pre workout powder scoops or pills 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, taken in proper dose combined with enough push in your routines.

You know how people 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 thermogenics 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! 

But a crash fat loss move doesn't ever equate with starving, so here's a compiled list of preworkout snacks that definitely doesn't conflict with fat burning.

Popular & Effective Thermogenic Ingredients To Look For

While most regular pre workouts will contain similar ingredients, the hybrid thermogenic 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 pre workout being the best, be on the lookout for these main key ingredients to get the best 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, thus making it one of the great thermogenic ingredients.

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, which is usually found in coffee, ginseng and other stimulants are great when taken in the morning, be careful though, and avoid too much coffee or any other source of caffeine later in the afternoon/evening as it will keep you from getting a restful night’s sleep and hamper your recovery.

If you want to go easy with caffeine or if you have concerns about your blood sugar levels increased, but not into giving it up, try the ones with green coffee bean extract to get the best of both worlds!

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 thermogenic 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 well being of your nervous system instead of overstimulating it and potentially making you jittery.

Capsaicin / Cayenne

Capsaicin is one of the best-known thermogenics 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 pre workouts 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, although less known like beta alanine; 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 the much needed sustained 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 people that we can and should take a thermogenic pre workout supplement every single day, the reality is that you need to cycle it.

This means using a pre workout thermogenic fat burner supplement for up to 6-10 weeks in a row before taking a 4-6 week break before using it again.

Here's the deal:

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

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. And this is true for both men and women alike, when it comes to taking supplements.


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 burning / heat generator, but what else can these pre workout thermogenic fat burning supplements do?

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

  • Boosts metabolism for 24/7 due to its calorie burning ingredients
  • Increases focus & sustained 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 cons, 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 servings of it 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 to keep you hydrated.

It is also wise to go creatine free as caffeine and creatine don't work together. As you may probably already know, caffeine is a diuretic which basically makes us lose water, while creatine makes us hold on to it. Bottomline is that they cancel each other out. Better have one OR the other.   

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!


In your efforts to gain a strong body and lean muscle, intense training and a healthy diet are your most powerful tools. You can jumpstart your diet with healthy snacks, too.

However, a good; or better yet, the best pre workout supplement formulated with fat burning ingredients can greatly boost the effects of your hard work, giving you additional firepower to get rid of unwanted body fat.

If you are into losing weight and burning fat, you also may want to make sure you do cardio work where you raise your heart rate for a prolonged period. Look at our list of supplements for cardio right here.

Similar to all life aspects, you reap what you sow, and the same principle applies to acquiring lean muscle. You can't just pop a pill or powder and expect to achieve your dream body without proper training and suitable nutrition.

A thermogenic pre workout fat burner powder or pill supplements work in concert with your other efforts to give you the results you want.
