Nutrition around training is one of the most practical levers available to anyone who exercises regularly — yet it is also one of the most misunderstood. What you eat before a session shapes your energy levels and endurance. What you eat afterwards determines how quickly your muscles recover and how effectively your body adapts to the training stimulus. Getting both right does not require a complicated approach; it requires understanding a few core principles and applying them consistently.
What to Eat Before a Workout
The primary goal of pre-workout nutrition is to ensure your body has sufficient fuel for the effort ahead, without causing digestive discomfort during exercise. The key macronutrient here is carbohydrate — the body's preferred energy source for moderate-to-high intensity activity.
Carbohydrates and Timing
Carbohydrates with a low to moderate glycaemic index (GI) are best suited to a main pre-workout meal, as they provide a more sustained release of glucose into the bloodstream. This is particularly relevant for longer training sessions. For short, high-intensity efforts, faster-releasing carbohydrates consumed closer to the session can be appropriate.
As a general rule, aim to eat a full meal containing carbohydrates and a moderate amount of protein 2–3 hours before training. If you need something closer to your session, a light, carbohydrate-focused snack 30–60 minutes beforehand is a practical option. Keep fat and fibre intake low in the immediate pre-workout period — both slow gastric emptying and can cause discomfort during exercise.
Pre-Workout Meal Ideas
Simple, effective options include oat porridge with fruit and a scoop of protein powder, a wholegrain wrap with grilled chicken and vegetables, natural yoghurt with nuts and honey, or a smoothie blending a banana, plant milk, oats, and a serving of protein. The goal is a meal that is light enough to digest comfortably but sufficient to fuel your output.
Hydration is equally important. Arriving at a training session even mildly dehydrated measurably impairs performance. Drink water consistently throughout the day and consider an electrolyte drink before longer or more intense sessions, particularly in warm conditions.
[tip:If you train early in the morning and cannot eat a full meal beforehand, a banana or a small portion of quick oats with protein 20–30 minutes before training is usually enough to prevent early fatigue — especially for sessions under 60 minutes.] [products:powerbar-powergel-shots-gums-orange-60-g, vitalers-isotonic-lemon-lime-powder-250-g, ostrovit-electrolyte-90-tablets, powerbar-electrolytes-no-sugar-mango-passion-fruit-10-tablets, sunwarrior-warrior-blend-protein-chocolate-usa-750-g, beorganic-pea-protein-powder-200-g]What to Eat After a Workout
Post-workout nutrition serves a fundamentally different purpose: recovery. During exercise, muscle fibres sustain micro-damage, glycogen stores are partially depleted, and the body enters a heightened state of nutrient uptake. The window immediately after training — roughly 30–60 minutes — is when your muscles are most receptive to the nutrients required to repair and grow.
Protein for Muscle Repair
Protein is the centrepiece of post-workout nutrition. Consuming 20–30 g of high-quality protein after a session provides the amino acids necessary for muscle protein synthesis — the process by which the body repairs and rebuilds muscle tissue. Whey protein is the most researched option and is particularly effective due to its rapid absorption and high leucine content. Plant-based protein powders are a reliable alternative for those who avoid dairy, though they may benefit from combining complementary sources (such as pea and rice protein) to ensure a complete amino acid profile.
Carbohydrates for Glycogen Replenishment
Carbohydrates consumed after training help replenish muscle glycogen, particularly important after intense or prolonged sessions. A practical target ratio of carbohydrates to protein of approximately 3:1 supports both glycogen synthesis and amino acid uptake simultaneously. Good post-workout carbohydrate sources include rice, potatoes, oats, bananas, and other whole food options. Faster-release carbohydrates can be appropriate immediately after very intense training.
Post-Workout Meal Ideas
Effective recovery meals are straightforward: brown rice with baked salmon and steamed vegetables covers carbohydrates, protein, and anti-inflammatory omega-3 fats in one serving. A protein shake blended with milk, a banana, and a tablespoon of nut butter is a fast option when a full meal is not immediately possible. Cottage cheese with fruit and nuts works well for evening recovery sessions. A veggie omelette with a side of whole grain toast is another simple, practical choice.

Whole food should form the foundation of any sports diet. Supplements serve a supporting role — filling gaps that are difficult to address through diet alone, or providing nutrients in formats more convenient around training.
Protein powders are among the most practical supplements for active people, making it easier to hit daily protein targets without significantly increasing calorie intake from fat. Whey concentrate and isolate are fast-absorbing, making them well suited to post-workout use; plant-based blends serve the same purpose for those who avoid animal protein. Browse our protein powders collection for the full range of options.
BCAAs (branched-chain amino acids) may be useful during prolonged fasted or low-carbohydrate training, and for individuals whose total protein intake is borderline. Creatine monohydrate remains one of the most well-evidenced supplements in sports science, supporting strength, power output, and recovery from high-intensity efforts — it can be taken at any time of day with consistent results. Electrolyte supplements and isotonic drinks are particularly relevant for anyone training in heat, sweating heavily, or completing sessions lasting over 90 minutes. Explore our isotonic drinks collection for hydration options suited to training.
[tip:Creatine does not need to be taken at a specific time relative to training — consistency matters more than timing. A daily dose of 3–5 g is sufficient for most people, with no loading phase required.] [note:All products available at Medpak ship from within the EU — no customs delays or additional import fees for customers across Europe.]
