What is Pre-Workout?

If you’ve been to the gym before, you’ve probably heard all about pre-workout, but if you’ve been living under a rock, we’ll lift the lid.

Pre-workout is one of the Essentials to Take to the Gym, providing you with energy, aiding endurance and helping build power. If you struggle to ‘get in the zone’, feel overly tired and lethargic, or want to push yourself to perform harder, you might want to add a pre-workout to your stack.

Pre-workouts contain a core of powerful ingredients, spearheaded by caffeine (unless you get a non-stimulant pre-workout) and supported by an ensemble of components like creatine, beta-alanine, BCAAs, nitric oxide precursors and more (Landes, E et al. 2021).

What are Stimulants in Pre-Workout?

Caffeine is the primary stimulant used in pre-workouts due to its energy and focus-boosting properties. Caffeine can help to improve alertness and exercise performance and may help you train for longer while delaying fatigue (Landes, E et al. 2021).

Because the major stimulant in pre-workout is caffeine, you may experience side effects if you consume too much. So, if you love your early morning coffee (and your mid-morning, late-morning, and early lunch coffee, too), then it may be safe to choose a pre-workout with a lower dosage of caffeine.

A typical pre-workout will generally contain between 150mg to 300mg of caffeine per serving, which is close to the same force as three cups of coffee (caffeine content in a cup of coffee varies based on the type of bean, roast style, serving size and preparation, but a typical shot of espresso contains about 63mg of caffeine) (Bjarnadottir, A. 2017).

If you’re a heavy coffee drinker, don’t worry; caffeine isn’t the only stimulant used in pre-workouts! There are a number of natural stimulants that are included in pre-workouts that can still boost your energy the same way caffeine does. Ginseng, L-Theanine, Guarana, Theobromine and others can naturally stimulate and boost your cognitive function (Shields, T. 2022).

High-Stim Pre-Workout

If your tolerance to stimulants is high and you’re no longer feeling the power of your standard pre-workouts, then you might find you need something that packs a little more punch.

Among our range of Pre-Workouts at ASN, we offer a range of the Strongest Pre-Workouts that you can get your hands on.

Crank yourself up with Crank pre-workout, one of our most popular powerups that can enhance your muscle pumps, lift your mood and enhance your performance without causing any jitters. Faction Labs can deliver razor-sharp focus with Disorder while helping to increase your strength and supporting superior muscle pumps.

This full-strength formula is built with highly effective and trademarked ingredients that can boost your cognitive function, intensify your energy and give you the strength to persevere through even the toughest of workouts.

Low-Stim Pre-Workout

Sometimes those stims can pack a little too much punch, especially if you’re not willing to sacrifice your daily coffee. That's okay; we also offer Low-Stim Pre-Workouts to feed you a healthy bout of energy without any unwanted jitters.

Naked Harvest has formulated a Natural Pre-Workout that can invigorate you with a blend of plant-based amino acids, vitamins and green tea extract to give you a natural, low-stimulant boost.

Pure Boost built its blueprint with 3000mg citrulline malate to increase nitric oxide levels while utilising caffeine anhydrous and a range of other ingredients to deliver the best recipe for a successful performance.

Non-Stim Pre-Workout

Whether you’re sick of caffeine, find yourself suffering jitters or a post-training crash, or prefer the late-night gym sessions and want to actually get some sleep afterwards, you need a Non-Stimulant Pre-Workout.

You have your pick of the best when it comes to non-stimulant pre-workouts, with our stores only supplying the highest quality supplements to enhance your performance. If you’ve tried Faction Labs Disorder before but want a stimulant-free alternative, Bulge by Faction Labs is the perfect replacement.
