2025 Pre-Workout Guide

In the ever growing, ever changing world of pre-workouts, it’s easy to get confused and get a pre that doesn’t hit the way you want it to. Choosing the wrong pre can leave you awake at 3am because you took 500mg of stimulants, itching your face off and having a bad session. That’s why we’ve put together a list of our top pre-workouts in each category, in no particular order. Stim Free Pre-Workouts Stim free pre-workouts are usually for the PM crew. The late night lifters. They can also be beneficial to those taking a stimulant break, those sensitive to caffeine or those who just don't want any. These pre-workouts put more emphasis on your pumps, endurance, power and focus. Making sure you’re able to relax when you leave after your late night session. Transparent Supplements Pump Juice: Loaded with a formula that lives up to its name, Pump Juice is packed with ingredients that deliver muscle pumps, power, endurance and hydration. An all in one non-stim pre. Primabolics Grind V2: The newly improved version of Primabolic’s Grind pre has a packed formula that’ll give you the best pumps, power and focus. Now with added electrolytes and glycerol to make sure you’re hydrated and ready. Performax VasoMax: If you’re after maximum pumps, VasoMax by Performax has 4, yes 4 trademarked pump ingredients that are clinically proven to get you a massive pump. Mid-Stim Whether you’re new to pre-workouts, trying to avoid tingles, or just don’t want too much caffeine, a good mid-stim pre workout will still perk you up for a good training sesh. But not so much that you can taste colours. Zombie Labs Infected: With a nice 325mg of caffeine, 6g of citrulline and no beta alanine. Zombie Labs Infected will deliver energy, pumps and focus, without the tingles and itches of beta alanine. Ghost Legend V4: The fourth iteration of Ghost’s Legend pre gives you 300mg of natural caffeine, mixed in with Nitrosigine for pumps and a focus blend. Making sure that you have a lasting performance boost. Rule 1 PreLift: If you’re after a pre that makes you feel like you can train forever, look no further than PreLift. A total of 335mg of 3 different caffeine that have staggered releases, nootropics, pumps, and endurance ingredients for days. High-Stim If tasting colours is more your thing, then look no further than a high-stim pre. Made for those early mornings, full send weekend sessions, or those who need a fair hit of stimulants to kick their workouts into gear. Zombie Labs Cross-Eyed: And extreme pre with extreme dosings. 400mg of caffeine, added stimulants, 6g of citrulline and 4.2g of beta alanine. You’ll be pumped, energised and itching. Nexus Per4m: Another one boasting 400mg of caffeine, 6g of citrulline, added stimulants and 3.2g of beta alanine. Made for next level energy. Primabolics ProFormance: Primabolics coming in with one of the most complete pre’s on the market. Energy, Endurance, power, pumps, focus and hydration are all ticked by Proformance. Death By Stims If high-stim is, somehow, not enough for you, and you want a pre that is similar to jet fuel. These pre’s will get you up, ready and pumped. These pre’s are not for the faint of heart and should be taken very seriously, and not around bedtime. Zombie Labs End Of Dayz: This pre has birthed a whole new pre workout genre. Crowned the strongest pre workout in Australia, with 480mg of caffeine, 2g of nootropics, 10g of citrulline and 5.5g of beta alanine. Yes you read all of that right. Nexus Per4m 2.0: Nexus’ answer to End of Days, with a mythical 500mg of caffeine (yes, half a gram), 10g of citrulline, 5g of beta alanine and creatine to round it all out. The X Athletics Dialed Carnage: With a mega dose of 525mg of caffeine in ONE SCOOP, Dialed Carnage lives up to its name by making sure you’re absolutely dialed in for your workout. Scoop Smarter If you’re training at 5am, 5pm and everything in between, there’s a pre that fits your needs. Picking what one suits you best can mean the difference between a solid session and feeling your heart beat in your ears. Remember to double check the label and make sure that it fits what you’re looking for.

What Is A Calorie?

Whether it be dieting or exercising, having even a baseline understanding of what calories are and how they make up certain foods, is essential to achieve long term success with your goals. But what is a calorie actually? How much of these calories make up the macronutrients present in our everyday lives? Macronutrients & Calorie Density Firstly, it’s common knowledge that there are three main macronutrients that the body ingests and uses the nutrients from to run on a day to day basis. These macros each have a very specific role to play in the body’s functions, and all have different caloric amounts; Carbohydrates - 4 calories per 1g These are the body's primary source of energy. When consumed, carbs are broken down into glucose, which is used by the body for fuel. Carbs also play a role in the storage of energy in the form of glycogen, which can be accessed during physical activity. Fats - 9 calories per 1g These are made up of fatty acids and glycerol that are essential for many vital functions. Fats help absorb fat-soluble vitamins (A, D, E, and K), support cell structure, and protect vital organs by providing cushioning. Additionally, fats are involved in hormone production and help regulate body temperature. Proteins - 4 calories per 1g These are made up of amino acids, which are the building blocks of the body. They play a crucial role in repairing and building skeletal tissue, skin, and organs. Proteins are also important for producing enzymes and hormones that regulate several bodily functions, including metabolism and immune response. Foods found at the supermarket, made at home and bought out, are made up of these macronutrients, the macros you’re eating all have a caloric amount. Therefore, when you meal prep and have a high protein meal for example, it tends to be lower in calories because you may not cook the chicken with oil, or you’ll have extra vegetables instead of extra rice, you’re digesting macros with a better calorie to gram ratio and being more conscious of how the food is cooked. Pretty Obvious Right? Most of this information is readily available, and if you’ve progressed from being a novice in gym, you’d have an understanding of how those calories are burnt off in the same way. What’s important to remember though, is that a reminder can go a long way. If you’re struggling to lose weight for example, and you’ve prepared meals all week, not eaten out and stayed super strict on your diet, but you’ve stayed the same weight or maybe even gained, it may be because of the process you’re cooking your food in. The Bottom Line All in moderation and with balance is a very popular saying right now within lifting and dieting circles, it couldn’t be more true. At the end of the day, this information isn’t to ward yourself off of certain foods, but to become more aware of the processes and ways you can enhance your training and overall quality of life. There’s no need to remember how many calories a teaspoon of oil is or the grams of avocado on your toast, but be conscious of your goals whenever the opportunity comes.

Unlock Your Energy Potential: Why NAD+ is the Supplement You Need

Energy, It’s the backbone behind everything fitness. Workouts, recovery and even just normal bodily functions need energy. What’s the energy source behind all this? NAD+, short for nicotinamide adenine dinucleotide, doesn’t have the flashiest or even most well known name in the industry, but don’t let that fool you. NAD+ plays a massive role in how your cells produce energy, recover and even age. Whether you’re an athlete, or just want to age more gracefully, NAD+ is the supplement worth knowing about. What is NAD+? NAD+ is a coenzyme found in every cell that resides in your body. Its job is to help your mitochondria create ATP, so your cells have usable energy. NAD+ is also a big player in your body’s metabolic function, cellular repair and even DNA health. As we get older, NAD+ levels decline, leaving people with slower recovery, reduced energy, brain fog and tired skin. This is why supplementing with NAD+ has become a trend for those who want to wind back the clock a bit. The best part? It’s backed by science. NAD+ Precursors: What to Look For Now for the bad news. NAD+, when taken as a direct supplement, doesn’t absorb well into your body. Don’t let that put you off, there’s a work around, precursors. Precursors are compounds that, when taken, convert into NAD+ inside your body. The main one that you’ll see on the market in NMN (Nicotinamide mononucleotide). If you’re looking for NAD+, NMN is highly bioavailable and will raise your NAD+ levels no worries. Benefits of NAD+ & NMN Supplementation So I’ve got your attention when it comes to NAD+. Want to hear the benefits too? Here are the highlights More Energy: Within a few weeks of consistent use, users noticed that they feel more energised and less tired. Faster Recovery: With the reduced inflammation and improved cellular repair, post- training recovery becomes a breeze. Anti-Ageing Effects: It’s no fountain of youth, however NAD+ has been shown to help you age more gracefully by protecting cells from oxidative stress and DNA damage. Mental Clarity: Brain function, memory recall and reducing mental fatigue all gets a nice bump from higher NAD+ levels. How to Increase Your NAD+ If you’re looking to raise your NAD+ levels, take NMN daily, like a multivitamin or creatine. Start with a 500mg daily dose and see how you feel after 1-2 weeks. From there you can work your way up to 1000mg, which is the maximum dosage. Taking too much NMN, or too much NAD+, can cause side effects like nausea, headaches, skin issues and liver strain. Starting at the bottom end of the recommended doses, and adjusting as you go will make sure you’re safe. Conclusion Increasing your NAD+ levels through NMN may not be the first thing you look at when choosing your supplements, but it is definitely one of the most important ones that you can add. Supporting energy and the cellular level, improving recovery, and having multiple long term benefits, a NAD+ precursor supplement is worth adding into your daily stack.
