Pre-workout supplements have become a training staple on a par with protein powder, and with good reason—they're effective and easy to use. So easy to use, in fact, that the very name tells you exactly when to take it.

In light of that See-Spot-Run simplicity, how could someone mess up their pre-workout? You'd be surprised. Make sure you're not making any of these mistakes when it comes to this popular supplement category.

Mistake 1: Your Timing is off (Seriously)

I often see people drinking their pre-workout as they're walking into the gym. Most of the active ingredients in your pre-workout drink take 30-60 minutes to reach peak levels in your blood. If you wait until you reach the gym to take it, you'll be well into your second or third exercise before the full effects kick in.

Can you take pre workout before work

And if you think taking your pre-workout too early will leave you short on energy halfway through your workout, think again. Most pre-workouts are stimulant based, and that stim is usually caffeine. It takes your body 3-5 hours to cut the concentration of caffeine in your blood in half.

So if you have it anywhere from 30 minutes to an hour before your workout, you're getting the full benefit from it. A bigger concern should be whether you're taking it too late, especially if you work out in the late afternoon or early evening, If you do, you may have trouble falling asleep afterward.

Mistake 2: You're Taking it on an Empty Stomach

If you ever drink coffee on an empty stomach, you know the feeling: light-headed, jittery, and sometimes even nauseous. If you drink a pre-workout with 200-300 milligrams of caffeine without eating anything, you can feel exactly the same way.

Having a small meal 30-60 minutes before you take your pre-workout can help minimize side effects like these—plus, those extra nutrients will help you push through your workout.

If you're concerned that taking pre-workout on a full stomach will reduce its potency, don't eat a meal with a lot of fiber in it. Avoid whole grains, raw fruit, nuts and seeds, and raw vegetables.

Mistake 3: Your Pre-workout is Missing Some Basic Ingredients

There are lots of great pre-workouts to choose from these days. There are also lots of less-than-great pre-workouts—often the ones with more ingredients than you can count on your fingers. A long list of ingredients probably includes fillers, or such small quantities of important ingredients that a single dose won't do you much good.

My advice is to stick with basic ingredients. Whether you pick your pre-workout based on flavor, label, or brand name, just make sure it has the following ingredients:

  • Caffeine: for the extra energy you need to crush your workout and fight fatigue for one more rep!
  • Citrulline malate: for getting oxygen and nutrients to your muscles, and providing extra energy to boost your performance.
  • Creatine monohydrate: to boost muscle mass and strength gains. Creatine can be taken at any time of day, but making sure it's in your pre-workout is a great way to get at least one dose in each day.

What Does Pre-Workout Do?

If you don't fuel yourself properly before exercises or hard workouts, you'll be less energised, weaker and will fatigue faster than normal. That's a fact. Pre-workout is designed to help fight this, to help you keep going harder and for longer. So while the supplement can be taken in a variety of formats — from meals to shakes to pills and more — they're all designed to boost energy levels and increase focus.

For many, pre-workout supplements are usually mixed with a drink and taken around 30 minutes before the beginning of a workout. That's because, by supplying your body with extra carbohydrates, the glucose in the pre-workout helps raise blood sugar levels and supply additional energy during a workout. In short, they're much more energising than a banana, shot of espresso or a black coffee.

What's in My Pre-Workout and Is It Safe?

As a pre-workout is designed to help you cruise through a particularly tough workout, it shouldn't be a surprise to learn that they supply your system with sugar, caffeine and other energy-boosting stimulants.

But it pays to read the ingredients label before you invest in a fresh pot of pre-workout. Caffeine is the key ingredient to look out for as the content can vary from mild to way too much, and in extreme cases, high levels of caffeine can cause some pretty serious health issues like anxiety, insomnia and high blood pressure.

For most men, however, pre-workout is a safe supplement to take, but, even at the safe end of the spectrum, its side effects can still cause jitters, itching and interrupted sleep, which are harmless but still uncomfortable. Our advice: if you're new to pre-workout, go for half doses to begin with and see how your body reacts.

What Pre-Workout Ingredients Should I Look Out For?

Creatine Monohydrate: A popular supplement among gym-goers, creatine is included in many pre-workouts due to its potential to increase muscle power and performance during training.

BCAAs: Branch chain amino acids have been found to improve endurance during a workout and increase strength by maintaining cellular energy and supporting protein synthesis.

Taurine: Found in various animal meats, taurine is a sulfonic acid that contributes to the metabolism of fats and fights oxidative stress during workouts.

B-vitamins: Vitamins B1, B2 B5, and B6 all play important roles in energy production and efficiency, while Vitamin B12 supports blood production and Vitamin B3 boosts DNA repair and promote healthier skin.

NO2-boosters (ex. Arginine, Citrulline): Arginine, for example, is a nitrogen dioxide booster and an amino acid that acts as a 'vasodilator'. Essentially, arginine (and other similar nitrogen dioxide supplements) expand your veins and arteries, making it easier for blood to flow around your body, delivering nutrients quicker and more efficiently.

What Pre-Workout Ingredients Should I Avoid?

Research published in Food and Chemical Toxicologycited that 400mg of caffeine a day is the upper limit for adults. What does this mean to you? One cup of instant coffee contains 60-80mg of caffeine, but high street flat whites contain anything between 65mg (Pret-a-Manger) and 160mg at Starbucks.

Some pre-workout brands spill over the recommended daily dose. ProSupps Mr Hyde NitroX pre-workout, for example, houses an uncomfortable 410mg of caffeine in a 7.5g scoop.

As sports nutritionist Matt Lovell points out, there are definitely some pre-workout products that you should actively avoid. "I would say any speed cousins, amphetamine cousins. Some pre-workouts basically contain ecstasy. Or close to it," he says.

Is Pre-Workout Dangerous?

Broadly speaking, pre-workout supplements — like the products we've listed below — are safe to take on a regular basis when following the manufacturer's instructions. Of course, when it comes to ingesting caffeine, we all have different thresholds and, with some brands tipping over a sensible limit of caffeine content, it can become a risky game.

Research published in the Food and Chemical Toxicology journal cites that 400mg a day — that's around two to three cups of coffee — as the upper limits for adults, so be sure to check the per-serving caffeine content of your chosen pre-workout during your next supplement top-up.

How Long Does Pre-Workout Take to Kick In?

When you start your workout, you want to hit the ground running. You don't want to be waiting around for your pre-workout to kick in, so it pays to find the sweet spot to take it. For most people, the ideal time to take you pre-workout is around 30 minutes to one hour before your workout — this should give the supplement enough time to hit your bloodstream and amp you up ahead of your session.

Something to consider, however, is the 'half life' of caffeine. Generally, caffeine has a half-life of around three to seven hours after ingestion. If you're used to training in the evenings, you want to take half the recommended dose or swap it out for a pre-workout alternative. We've listed a few below.

When Should I Take Pre-Workout?

The all important question: if you're going to boost your performance with pre-workout, when is the optimum time to take it? Well, like we've mentioned, most people take pre-workout around 30 minutes to one hour before they workout, but just because it's called pre-workout that doesn't necessarily mean you have to take it prior to your workout. "For longer sessions," says Lovell, "you could delay until an hour into the session." Always refer to the label of your pre-workout for specifics.

Should I Take Pre-Workout Every Day?

If you continue to take pre-workout on a regular basis, your body can build up a tolerance to its effects, which is why Lovell advises cycling the supplement, or coming off it for six to eight weeks at a time to give your body a chance to reset. "Cycling is the way forwards," he says. "Also get some stimulant-free ones [that] you can use most days or just some plain old tyrosine which is a very good budget pre-workout."

Can I Use Coffee as a Pre-Workout?

As we've mentioned, coffee and pre-workout share a common primary ingredient — caffeine. Found to have an effect on improving athletic performance, coffee also doesn't contain the additives and additional ingredients that other pre-workout supplements may have. Studies have shown that caffeine concentration peaks at about 45 minutes after ingestion, with effects lessening thereafter.

Simply put — yes, you can use coffee as a pre-workout.

The Pros and Cons of Taking Pre-Workout

Pros

  • Improved performance: Research published in the Journal of the International Society of Sports Nutrition concluded that pre-workout supplements "have promise as an ergogenic aid for active individuals," or, in other words, they enhance the performance of people who already exhaust the gym.
  • Increased concentration and focus: Pre-workout is packed with caffeine, which is know to enhance cognition. As research published in the Journal of Alzheimer's Disease found, caffeine works on people's arousal, mood and concentration, so if you want to be focused on a workout, pre-workout is the supp for you.
  • The University of Córdoba found the citrulline added to pre-workout could add up to 53% more bench press reps in a workout.
  • In another study, pre-workout containing citrulline was found to give cyclists a 12% longer ride before hitting exhaustion.

    Cons

    • Negative side effects caused by overstimulation: if the jitters and interrupted sleep we mentioned earlier don't sound like fun, perhaps give pre-workout a miss.
    • You can build up a tolerance with overuse: if taken excessively, your body can become immune to pre-workout's effects. To avoid this, it's probably best to save pre-workout for those sessions where it's either 'go hard or go home' or try cycling the supplement once in a while.
    • Can cause digestion problems: ingredients like sodium bicarbonate, magnesium, creatine and caffeine can all cause digestion issues. Avoid this by trying different pre-workout supplements until you find one that works for you.
    • Scientists have previously linked the original class of energy drinks to diabetes, mental health problems and kidney damage.

            Bananas: Rich in starchy carbohydrates, one banana will contain around 14g of sugar, made of glucose and fructose – two sugar types that are ideal for athletic performance. Similarly, bananas are rich in potassium and magnesium, providing electrolytes to your body that — when lost — will cause muscle cramps and fatigue, so it's best to keep your levels topped-up. Each banana will contain around 20-27g of carbohydrates, fuelling your muscles before strenuous exercise.

            £1.99

            Coconut Water: Like bananas, coconut water is naturally full of electrolytes. With an improper electrolyte balance leading to muscle cramps, stiffness, nausea, headaches and fatigue, drinking coconut water will help top up your body's electrolyte supply. You'll want to ditch your energy drink too, because coconut water contains more nutrients per serving and up to 25% fewer calories when compared to market-leading sports drinks.

            Can I take pre

            Product makers say pre-workouts can keep you focused, give you energy, and improve your overall performance. The main ingredient behind these promises is high levels of caffeine. Pre-workout supplements have a range of 150 mg to 300 mg of caffeine per serving. This equals about three cups of coffee.

            Can I use pre

            If your pre-workout supplement contains caffeine or other stimulants, it may inhibit your ability to fall asleep or stay asleep. Unless you have a high tolerance for caffeine, pre-workout will likely affect your sleep if taken too close to when you go to bed.

            Can you take pre

            The simple answer is yes, you can take pre-workout at any time. However, the best time to take pre-workout is about 30 minutes before your workout. This will give your body enough time to absorb the nutrients and provide you with the energy you need to power through your workout.

            When should you not take pre

            Caffeine can last anywhere from 3-5 hours. With that being said, if you plan on Jumping into bed around 11 pm, you shouldn't take your pre-workout supplements after 6 pm or they might affect your sleep.
