Pre Workout Products

This introduction to pre workout supplements will give you the facts about one of the most popular categories in the sports nutrition industry.

Before we dive right in to the pre workout reviews, let’s look at what they are and what they are supposed to do.

Simply put, pre workout supplements, as the name suggest, are taken before a workout and are designed to enhance the performance of the workout by providing more energy, more stamina and increasing overall muscle building potential. These are the benefits of pre workout supplements, but with all the products out there, each boasting they are the best, how do you know which one to choose?

It must first be noted that pre workout supplements are not mandatory to achieving your goals. Sure they can help but may not be for everyone –especially since most pre workout supplements contain stimulants and thermogenics.

But let’s face it. If you’ve spent enough time in they gym, you’ve experienced that feeling of fatigue; maybe a mental fatigue where it was difficult to concentrate. Maybe you just didn’t have that inner motivation to power through your reps. You’ve been there and so have we. That’s where pre workout supplements can benefit you tremendously.

Different Types of Pre Workout Supplements

There are a variety of different types of pre workout supplements you can take. These include:

Whey Protein

Hold on you say! Everyone knows that you take your protein shake after a workout.

Actually, there is a ton of evidence that taking whey protein before (as well as after) a workout can help fuel the muscles during the workout -especially the BCCA’s, a.k.a. the branch-chained amino acids. These truly are the building blocks of muscle and the trio of amino’s… leucine, isoleucine and valine, do not get processed by the liver but shoot straight to your muscle.

When you are breaking down muscle during a workout, having the BCCA’s in the bloodstream readily available to be utilized by the muscle increases protein synthesis and maximizes your workout.


Thermogenesis is the energy your body uses during metabolism to burn calories. Pre workout Get Ripped Using Pre Workout Suppsthermogenics focus on this metabolic

fat-burning potential in the gym. Thermogenics usually contain stimulants that increase the heart-rate and increase the metabolic rate so may not be appropriate for stimulant-sensitive people. They are similar in nature to fat burning diet pills but can be a terrific tool to elevate your workouts by providing more energy, more stamina and more mental focus.

Nitric Oxide

In a very simple explanation, nitric oxide expands the blood vessels, improving blood flow and delivering more oxygen to virtually every area of the body –including the muscles. It is among the most popular type of pre workout supplement because it creates so many benefits during a workout. These include reducing fatigue during a workout, increasing overall performance, increasing available energy, elevates muscle pump. It just makes you far better in the gym…. period.


Caffeine is the world’s most popular drug. And it’s getting more popular in the gym. Caffeine is not perfect. An average cup of Joe may contain 70-80 mgs of caffeine. The average amount of caffeine in pre workout supplements can range from 200-300 mgs. Like any stimulant, caffeine can have negative effects on the body. It can over tax your adrenal glands, speed up the heart rate and cause high blood pressure.

But taken in moderation as a pre workout supplement can reap some very positive rewards. The most obvious benefit of caffeine (and why it’s the world’s most popular drug) is that it improves mental clarity and focus. But evidence suggests that caffeine can actually increase your strength in the gym. (If only Popeye knew that he could drink a shot of espresso instead of gobbling spinach.) Caffeine is also a thermogenic that helps to speed up the metabolism and burn fat.

Creatine & Beta-Alanine

Creatine is perhaps the most well-known pre workout supplement and has been around for a long time. The basic benefit of creatine is increasing strength by increasing energy in the body. It is moleculary similar to ATP which is the energy created by our cells. Beta-Alanine also promotes strength and helps reduce the lactic acid build-up in the muscle.

There are other types of pre workout products, but this covers the main ones.
