When it comes to getting results in the gym, training is only half the equation. What you eat, when you eat, and how well you hydrate play a massive role in how you perform and recover.
If you’re doing CrossFit-style sessions, strength work, or high-intensity functional training, your body demands more than the usual “eat protein and veggies” advice. You need a system that matches your training. You don’t need perfection, but you do need a plan.
Here’s a deeper look at how to fuel your body properly, so you’re not just showing up to workouts, but performing at your best.
1. Eat to Match Your Output: Know Your Macros
Your body needs all three macronutrients to function well, protein, carbohydrates, and fats, but the ratio matters depending on your training.
Protein helps rebuild muscle. Aim for 1.6 to 2.2 grams of protein per kilo of bodyweight per day. A 70kg person would need roughly 112 to 154 grams of protein daily, spread across meals.
Carbs are your training fuel. For functional fitness, carbs aren’t your enemy, they’re your edge. Think sweet potato, rice, oats, or fruit before training to fuel effort, and after training to help with recovery. Low carb diets often undercut performance in high-output training.
Fats help with hormone regulation and long-term energy. They’re not for workout fuel, but they help you feel full and support your brain and body between sessions. Use quality sources like avocado, olive oil, and nuts.
2. Time Your Nutrition Around Your Training
This is where most people go wrong. Even if your food quality is decent, bad timing will limit performance.
Pre-Workout (1–2 hours before): A small meal with complex carbs and a bit of protein. Think: chicken and rice, Greek yogurt with banana, or oats with whey protein.
Intra-Workout (Optional): Only needed if training for 90 minutes or more. A sports drink or carbohydrate powder can help endurance, but for most 45–60 minute sessions, water is fine.
Post-Workout (within 60 minutes): This is when your body is ready to absorb nutrients. Prioritise protein and carbs. Something simple like a whey shake and banana works well if you’re not hungry yet.
Want to get leaner? Time your carbs around your workouts. Want to build muscle? Eat more carbs consistently throughout the day.
3. Hydration: The Overlooked Performance Booster
Even 2 percent dehydration can drop your performance. Water matters more than most people think.
Start your day with 500–750ml of water. Add a pinch of sea salt if you’re training in hot weather or sweating heavily.
During training, sip consistently. Aiming for 2.5 to 3 litres per day is a good rule of thumb, with more on hot days or double sessions.
If you often feel fatigued during workouts, or get muscle cramps, hydration is a good place to start troubleshooting.
4. Smart Supplement Use
Supplements are not shortcuts, but they can help fill the gaps.
Whey Protein: Convenient and easy to digest. Useful if you struggle to hit daily protein needs.
Creatine Monohydrate: One of the most researched supplements for strength, power, and recovery. Take 5 grams daily. It’s safe, effective, and cheap.
Magnesium and Electrolytes: Useful if you’re training hard, not sleeping well, or feeling drained. Many people are deficient without realising.
Caffeine: Can boost performance when used smartly. Avoid using it late in the day and don’t rely on it to mask poor sleep.
Skip the fat burners and trendy powders. Stick to basics and track how you feel.
5. What’s Your Goal? Eat for That.
Everything above should be shaped by your personal goal. Fat loss, muscle gain, improved performance, they each require slightly different adjustments.
This is where coaching matters.
If you’ve been guessing with your nutrition or following plans that don’t match your training style, it’s time to change that. You don’t need more restrictions. You need a clearer plan.
That’s what we do here. At Geelong Fitness, we help people train with purpose and eat to support that purpose.
