The majority of people I work with will always look for advice on a high-quality post workout protein supplement. And while it is the first thing I make sure they take after muscle-burning CrossFit workouts, I always try to encourage them to invest in a pre-workout supplement as well.

Yes, it’s arguably more important to recover faster and help your muscles heal and rebuild, but so many of my clients are totally surprised by how much better they can perform during CrossFit classes.

Over the years, I have seen the good, the bad, and the awfully bad pre workout supplements on the market.

So, our team here at Total Shape decided to put together a list of products that we generally recommend our clients.

Our Top Pre-Workouts for Crossfit (2021)

1 - Performance Lab Pre-Workout (Editor's Choice)

Performance Lab Sport Pre Workout Product Thermogenic PreWorkout

This is the top product our team was able to agree on as one of the best supplements for CrossFit training.

Due to the high intensity levels that you need to sustain for CrossFit, you need to make sure your muscles operate at maximum capacity.

One way to do that is through an increase in blood flow, which can be achieved through higher levels of nitric oxide.

The good news is that Performance Lab contains a good dose of L-citrulline which studies have confirmed can improve NO levels (1).

I see creatine monohydrate in a lot of the best pre-workout supplements due to the benefits of increased energy levels and endurance, as well as helping with muscle soreness.

  • Claims to raise nitric oxide for better pumps
  • Contains creatine to increase energy and speed up recovery
  • Stimulant free making it a good option for all times of day
  • Vegan-friendly option with natural ingredients
  • You need to take 4 capsules rather than a shake

The one thing to be aware of is that this is not a shake that you drink. You’ll need to swallow 4 capsules instead, which some review comments mentioned can be annoying.

2 - Jacked Factory Nitrosurge

3 Jacked Factory Nitrosurge

As the name suggests, this is a product that promises to raise your nitric oxide (NO) levels. With 3 g of L-citrulline, there is scientific backing to support this claim, especially from a recent 2018 study (2).

This brings more energy and oxygen to your muscles to provide better strength and impressive pumps.

Based on a lot of review comments, and Connor, our resident bodybuilder’s experience, this is a feature that has a lot of supporting evidence.

  • The primary claim is that it can increase blood flow for better pumps
  • Includes beta-alanine for more power and less fatigue
  • Combination of Caffeine and L-Theanine can help with weight management
  • Available in 3 tasty flavors (Cherry, Watermelon, Fruit Punch)
  • Doesn’t include creatine

One ingredient that is generally ranked highly for CrossFit is creatine. But the lack of creatine in this pre-workout is made up by the muscle pumps so many online review comments highlight.

Also, if you have any blood pressure or cardiac issues, then speak to your doctor before considering this one.

3 - Cellucor C4

Cellucor C4 Original Product

Cellucor has been a very popular brand at my gym, and I see a lot of men and women use it as their standard post-training protein.

However, their pre-workout is the product that stood out for me the most.

With the two main goals of CrossFit being muscle strength and fitness, Cellucor claims to address both of those through the inclusion of creatine.

One interesting study showed that creatine’s effects build up over time, which is ideal for an aggressive training plan (3).

  • Contains creatine for increased energy
  • A good boost of vitamins linked to muscle performance
  • Possibly one of the largest selections of flavors
  • Very good subscription options at an affordable price
  • Some amounts of ingredients are hidden behind proprietary information

On the downside, it does have one of my pet-hates, which is hiding behind proprietary labels for some of the ingredients. Overall though, the positive review comments convinced us to put it on this best-of list.

I would also suggest that you take a look at other Cellucor C4 Pre-Workouts products.

4 - Pre WOD

Energy Pre WOD thumb

What stands out the most about Pre WOD from a CrossFit perspective is the amount of beta-alanine it contains. According to Driven Nutrition, this provides the best results for high-intensity training periods that last 1 to 4 minutes.

There are countless online comments in forums where people mention that they saw a significant increase in power. I did a test with my colleague Connor where we did the same training routine a few days apart.

The time he used Pre WOD, he was able to lift more and do more reps than without it.

I would also agree with a lot of other user reviews that the available flavors are quite refreshing, and the powder is surprisingly easy to mix.

  • A strong dose of beta-alanine can boost performance
  • Includes caffeine from natural sources for a mental boost
  • Vitamin C boost to help improve nutrition delivery to muscles
  • Many review comments say it’s easy to mix
  • The amount of stimulants means you have to be careful taking it later in the day

While caffeine has a positive effect on your motivation for optimum performance, just avoid taking it later in the day. I’m speaking from experience with a sleepless night.

5 - Naked Pre Workout

Naked Pre Workout

Nope, this is not an invitation to strip off at the gym. Naked Energy is the clever brand name behind this pre-workout, which claims to deliver one of the cleanest supplements available.

Basically, it has a short list of active ingredients without any of the artificial crap that is so common just to make things taste better.

The combination of beta-alanine and creatine is great for CrossFit and any other workout designed for muscle building goals. And these benefits are highlighted in a lot of online reviews.

  • Contains a protein blend of beta-alanine and creatine
  • Has no artificial or unnecessary ingredients
  • A large amount of caffeine for a mental boost
  • Good subscription discounts available
  • Has a slightly bitter taste

The reason I don’t use this too often is that it does have a bitter taste to it and I just found it a bit difficult to swallow.

6 - Genius Pre

Genius Mind-to-Muscle Pre-Workout Powerhouse Powder

The Genius Brand has become very popular in the health supplements industry, and they have managed to create a product range that covers a very wide range of benefits.

The main ingredients are L-citrulline and beta-alanine, which are linked to improved lifting power and less fatigue, especially when taking it over a period of several weeks (4).

I also like having this available for when I go training later in the day as it doesn’t contain any caffeine that could end up in a sleepless night.

  • A good dose of L-citrulline and beta-alanine for power and performance
  • Claims to work well for physical and mental performance
  • Contains no caffeine or other stimulants
  • Comes with a 90-day money-back guarantee for a risk-free trial
  • Mixing it in a shaker can be difficult and may require blending

One thing I would agree with in some reviews is that it’s not the easiest product to mix in a shaker.

7 - Battle Ready Fuel Pre Workout

Battle Ready Fuel Pre Workout Product

I’ll admit, the name and labeling had me drawn in, but I was suspicious as fancy marketing usually means pre-workout supplements underdeliver.

However, Battle Ready Fuel managed to surprise me when I started reading all the positive reviews.

Part of the official product description highlights that the “energy boost comes from beta-alanine and citrulline malate,” and my dietitian was able to point me to a study (5) that confirmed a link to performance in aerobic exercises.

  • Claims to boost energy for workouts through a combination of citrulline malate and beta-alanine
  • An effective dose of caffeine to provide mental focus
  • Contains whey isolate and branched-chain amino acids (BCAAs)
  • The money-back-guarantee means you can try it risk-free
  • Strong dose of caffeine, so be careful with coffee intake

The only thing to be aware of is the strong doses of caffeine. While this is effective for fat burning and motivation, you want to be careful not to take it too late in the day.

Does Crossfit Require a Specific Diet?

Yes, CrossFit exercises require specific nutrition in order to help you get the most out of it. And, of course, you don’t want to be the one guy who falls down in a heap from utter exhaustion after the warmup routine.

As a CrossFit athlete, you will need plenty of energy in order to boost your performance, and protein is going to be a key part of your recovery phase. This translates into plenty of healthy carbs and a protein shake to help repair and build new muscle fibers.

However, there is one type of protein that can help the most.

Creatine has been linked to increased ATP production, which essentially is the raw energy your muscles need. So, if you really want to improve your success rate and performance, then pick one of the above products that contain creatine.

Adenosine triphosphate (ATP) is the most basic form of energy in your body's cells. It plays a fundamental role in metabolism and muscle function. Unfortunately, you can only store enough ATP for 8–10 seconds of high-intensity exercise. After this, your body must produce new ATP to match the demands of the activity

- Rudy Mawer, Sports Nutritionists


What supplements do CrossFit athletes take?

The most common supplements that CrossFit athletes take are pre and post-workout shakes, as well as some targeted BCAAs. These help to increase performance and speed up recovery so that you have a better chance of sticking with the CrossFit program.

What should you eat before CrossFit workout?

You should eat healthy carb-rich foods to boost your energy levels, but keep an eye on your calorie intake if you have weight loss goals. It’s also a good idea to get some extra magnesium into your diet to help with muscle performance and recovery.

What should you drink during a CrossFit workout?

You should aim to only drink water during a CrossFit workout and stay away from sugary energy and carbonated drinks. It’s also a good idea to get some extra electrolytes in before your workout, as they are critical for hydration.
