In this article, we answer the questions you need to know to get the best results from a thermogenic pre workout.
What is a Thermogenic Pre-Workout?
A thermogenic fat burner is designed to speed up the metabolism by raising your body temperature.
In doing so, it creates an environment in your body that is conducive to fat burning.
It does this with the aid of natural stimulants such as caffeine, green tea extract, and guarana.
Thermogenic fat burners boost your metabolism 24/7 while also making your workout more productive.
A good thermogenic will also address your appetite.
It will work on the satiety centers in the brain that help to keep your appetite checked.
Can Fat Burners Be Used as Pre workouts for Fat Loss?
Thermogenic Pre Workouts combine the effects of a thermogenic fat burner with those of a pre workout supplement.
They are designed to provide you with more energy, strength and focus for your workout while also speeding up your metabolism during the workout and in the hours after you leave the gym.
According to a study published in the International Journal of Obesity in 2005, thermogenic ingredients can boost fat burning potential by 10-15 percent (1).
Benefits of a Thermogenic Pre Workout
• Boosts metabolism to increase calorie burn 24/7
• Increased energy
• Improved focus
• Appetite suppressant
• Improves your workout performance
Key Ingredients to Look for in a Thermogenic Pre Workout
Caffeine is the world’s most widely consumed stimulant.
Studies have shown that it has the ability to speed up the metabolic rate by 8-11 per cent over a 12-hour period.
It also stimulates the production of adrenaline.
Caffeine also has the ability to boost the level of fatty acids in the blood, making them more readily available for energy (3).
Green Tea Extract
Green Tea Extract is an extract of green tea leaves.
It contains antioxidants mainly in the form of green tea polyphenols and catechins as well as caffeine, all of which are believed to aid fat loss by inducing thermogenesis, stimulating fat oxidation and increasing metabolism (4) (5).
Conjugated Linoleic Acid
Conjugated Linoleic Acid (CLA) is a fatty acid, primarily found in beef and dairy products, that has been shown to promote long-term fat reduction and health management.
Lab and clinical studies have also revealed that CLA promotes muscle tone as well as reducing cholesterol levels and boosting metabolism (6).
Capsaicin, an active ingredient in hot chili, increases core body temperature by boosting adrenaline levels.
It has been shown to increase workout calorie burn while also minimizing the effect of the body’s adaptive response to calorie reduction (7).
Best Time to Take It
For best results, you should take your thermogenic pre workout 30 minutes before your workout.
On no workout days, take it 30 minutes after waking up to produce an all day long metabolic increase.
Thermogenic pre workouts normally come as either a tablet, capsule or powder.
The stimulatory effects of these supplements mean that you shouldn’t take them within 5 hours of going to bed.
Thermogenic pre workouts should be cycled in order to prevent the body from developing a tolerance to the ingredients.
After using them for 8-10 weeks, take a 6-week break before cycling for a further 8-10 weeks.
Are There Any Side Effects?
Thermogenic pre workouts carry two key side effects:
• Lack of Sleep
Because thermogenics increase the body’s core temperature, the body needs more water in order to maintain its ideal body temp.
For this reason, you should drink more water when supplementing with a thermogenic.
The increased energy produced by the stimulants in thermogenics can affect sleep if taken within 5 hours of going to bed.
Stimulants such as caffeine may produce unwanted effects such as the jitters, headaches and a post-exercise energy crash if taken in large doses.
For this reason, you should not go beyond 400mg of caffeine per dose.
SKALD Oxydynamic Fat Scorcher is a thermogenic fat burner that is also designed to maximize your cardio and endurance output during training.
Ingredients are designed to relax and expand respiratory airways, allowing for increased oxygen consumption.
More oxygen means greater fat burning and more training energy.

This provides a range of proven stimulants and energy boosters without any added fillers.
Because this is a proprietary blend, the label does not state the individual ingredient doses.
This makes it difficult to know if you’re getting an effective dose.
However, it does provide a significant fat burning effect, while also noticeably increasing training energy.
The recommended dosage of SKALD is 1-2 capsules before eating in the morning and another capsule in the afternoon on an empty stomach.
Some people have reported experiencing heartburn when taking SKALD.
