Effective Pre-Workout

The number one goal of Outwork Pre-Workout is to help you have more effective workouts - not just once, but every time. Increased consistent performance translates to more PRs, more reps, and more volume, so you can build more muscle and improve body composition over time.*

Outwork Pre-Workout contains ingredients that have been demonstrated to decrease fatigue during anaerobic and aerobic exercise, as well as increase power output and strength. In addition to physical performance, Outwork Pre-Workout powder enhances your mental performance by supporting focus and cognitive function.*

Outwork Pre-Workout can help:

  • Support lean body mass*
  • Reduce excessive muscle damage*
  • Increase blood flow and nitric oxide production, leading to a better pump and more nutrients to your muscles*
  • Modestly increase fat oxidation*
  • Improve subjective feelings of well-being, potentially allowing you to train harder*

We're not here to sell you marketing mumbo-jumbo, just offer you science-based solutions that help you get more out of your workouts.

That's exactly what you'll get with Outwork Pre-Workout!

How To Use

To use the best pre-workout as a dietary supplement, mix two (2) scoops with 8-12oz of water. New Users should assess tolerance with one (1) scoop. Consume 30 minutes before training.

For maximum results, Outwork Pre-Workout is best used in conjunction with our Post-Workout Supplement and Whey Isolate Protein Powder.

Pre-Workout Ingredients

Citrulline Malate (6g per serving)

In humans, supplementation of 6 g of CM a day for 15 days led to a significant reduction in sensation of fatigue, an increase in the rate of oxidative ATP production during exercise, and an increase in post exercise recovery.[1]

Citrulline malate is a non-essential amino acid part of the ureogenesis cycle. Excess availability of CM enables the acceleration of this cycle, thereby facilitating the clearance of ammonium from the blood and tissues, which is a major fatigue factor. CM does so by stimulating glycolysis while blocking the aerobic utilization of pyruvate and recycling itself in the direction of gluconeogenesis. This results in less lactic acid accumulation and fatigue[2], making it a perfect ingredient for your pre-workout.

Citrulline malate increases nitric oxide production and reduces muscular fatigue through the reduction of lactic acid and ammonia in blood and tissue.[1]

Citrulline malate has been shown to significantly increase performance during upper and lower body multiple bout resistance exercise performance.[3]

Improves oxidative metabolism and exercise performance in healthy adults and enhances post exercise phosphocreatine recovery.[1][4]

Beta-Alanine (3.2g per serving)

On a total gram per day basis, beta-alanine dosing ranges from 2.4 to 6.4 g per day.[5][7] Other studies have broken down beta-alanine supplementation into 4 equal doses of 1.6 g per dosage. [6][8]

Beta-Alanine is a non-essential amino acid synthesized in the liver and taken up into skeletal muscle to yield carnosine, a histidine containing dipeptide. Carnosine acts as an intracellular hydrogen ion buffer to high intensity exercise, antioxidant and regulates muscle contractility.[5] However, it cannot be synthesized in skeletal muscle without Beta-Alanine acting as the rate limiting precursor. In isolated muscle, the absence of carnosine as a buffering agent leads to fatigue due to increased acidosis. Therefore, high levels of skeletal muscle carnosine is positively associated with anaerobic exercise performance.[7] 

Beta-Alanine improves muscle buffering capacity leading to improved resistance training quality by increasing the number of repetitions that can be performed at a given intensity of training.[6]

Beta-alanine delays the onset of fatigue by reducing muscle acidosis.[6]

Increases peak power output in high intensity exercise.[6][8]

Rhodiola (300mg per serving)

Rhodiola supplementation of 200-680 mg/day has been shown to improve physical performance while a dosage between 100-576 mg/day may reduce mental fatigue.[11]

Rhodiola is a medicinal plant which contains adaptogenic and biologically active substances in its root, including flavonoids and phenolic glycosides. An adaptogen is a natural herbal substance that helps the body adapt and resist damage caused by stress. The adaptogenic properties of rhodiola are attributed to its regulation of the hypothalamus pituitary-adrenal (HPA) axis and key mediators in the body’s stress response such as cortisol.[12]

Shown to reduce oxidative stress in blood, liver and skeletal muscle [11] (animal study).

Increases cognitive and neural performance [11] (in healthy males).

Increases overall health in mentally fatigued populations.[11]

L-Dopa (150mg per serving)

100 mg of L-dopa is effective in increasing mood in healthy individuals.[13]

The amino acid L-3,4-dihydroxyphenylalanine (L-DOPA) is a metabolite of L-tyrosine and the precursor to dopamine. L-dopa crosses the blood brain barrier where it is synthesized to dopamine in the central and peripheral nervous systems.[14] Mucuna Pruriens are a naturally occurring herbal supplement containing adaptogenic properties and high levels of L-dopa. They are typically referred to as the dopa bean.[15] Together they act as a nootropic agent to lower stress, improve mood, reduce anxiety, improve focus and boost libido [16], all very helpful in your pre-workout.

May improve cognitive function and mental alertness.[17][18]

Boosts libido and motivation.[19]

Decreases stress levels.[15]

    pretty good

    I bought the caffeine free to give myself a break from caffeine. Overall it is very good. My only complaint is that when it arrived it was hard as a rock and I had to use a knife to break it up to get it somewhat powdered again.

    Surprised me!

    I thought that my pre-workout "buzz" would take a step back without the caffeine but honestly I enjoy the feeling I get from this more. I feel a strong level of focus but can still fall asleep a few hours after my workout. Highly recommend and will buy again - although I will probably try a different flavor than tropical candy.
