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.

Are You Overtraining… or Just Under-Recovering?
If you’re diving into the rabbit hole of training, you’ve probably heard of the term “overtraining”. People claim that if you hit the gym too hard, don’t recover between sessions and maybe even go backwards, that’s overtraining. But, is it overtraining? Not likely The truth is, overtraining isn’t as common as you’d think. Under-recovery, however, is more common. If you don’t fix it, it doesn’t matter how perfect your program is, you won’t grow, hit that 1 rep max, and you’ll burn yourself out. What Is Overtraining and Under-Recovering? To clarify this: Overtraining mostly affects elite athletes or lifters with high training loads and not enough rest. It has physical and mental effects and can take months to recover from. Under-recovery is much more relatable. It’s when you’re smashing weights 7 days a week, sleeping 5 hours a night and not tracking nutrition at all. So, odds are you probably aren’t “overtraining.” But you might be under-recovering. Why “Overtraining” Isn’t a Thing for Most People You’ll hear the term get thrown around way too casually, but at the end of the day most people who think they’re overtraining are just not eating enough or sleeping enough to recover from their sessions. This puts you in a loop where you feel fatigued, sore and unmotivated. If that sounds all too real, overtraining isn’t the issue. Under-Recovery Might Be the Real Culprit Gains aren’t made in the gym, they’re made in the time spent recovering from your gym workout. Training is a stress on your body. Yes, stress is essential for growth, but it only works if you recover from it. If you’re not sleeping enough, eating enough, or training smart enough, the stress will snowball. After a while, your progress will stall and you may even go backwards. That’s under-recovery. Signs You’re Not Recovering Properly If you’re smashing the gym consistently but not seeing results, look out for these symptoms of under-recovery: Being sore for days on end Low motivation and fatigue Feeling exhausted but not sleeping Strength and performance hitting a wall Irritable and feeling “off” Losing your appetite Injuries that just won’t go away If a few of these sound all too real, it’s time to rethink your approach to training. How to Adjust Your Training for Better Recovery You can train hard, but if you feel like you’re in the bin most days, it’s time to train smarter. Here’s some adjustments you can make: 1. Track Your Intensity (RIR/RPE) If you’re slamming every set to failure, try backing off and leaving 1-3 reps in the tank. Save those all out failure sets for certain exercises. Using the RPE (Rate of Perceived Exertion) or RIR (Reps in Reserve) is a good way to track this. 2. Deload Every 4–8 Weeks If you’re going high volume for your training, having a deload week, where you reduce volume or intensity, can work wonders for your recovery. 3. Prioritise Sleep Up to 70% of your recovery happens during sleep, making it one of the most important things for recovery. Aiming for 7-9 hours per night is the sweet spot. 4. Eat to Support Recovery If you’re in a caloric deficit, your recovery will take a hit, there’s no way around it. Making sure you’re eating enough protein, and recovery will be the best it can. 5. Take Rest Days Seriously It’s not lazy to have a rest day, it’s a part of the program and a part of recovery. Having at least 1-2 rest days can make sure your body recovers. 6. Manage Life Stress Life is stressful. Everything from work to screen time can affect how you recover. A hard week at work + slamming weights at the gym all week = your body needing more to recover. You Don’t Need to Push Through Everything You’ve heard the “no days off” mindset, it’s easy to fall into. If you’re looking to progress long term, it’s a balancing act of intensity and recovery. Your training should challenge you, not cripple you. Once you fix the under-recovery, you’ll start to feel stronger and ready to push where it counts. Track More Than Just the Weight on the Bar If you’re feeling tired and stuck, it doesn't necessarily mean you’re overtraining, it usually means you’re under-recovering. Most lifters plateau from not supporting their recovery, rather than training too much. Recovery is the way that makes progress possible.
