Whatever your sport, proper nutrition is the foundation for results. Here are the key nutrition principles followed by professional athletes:
1.6–2.2 g/kg of body weight per day. Choose: chicken, fish, eggs, whey protein, plant proteins.
4–7 g/kg depending on the workload. Whole-grain products, fruits, vegetables. Before and after training.
0.8–1.2 g/kg. Avocados, nuts, olive oil, omega-3 fatty acids.
30–40 ml/kg per day. During sport: 500–1000 ml/h with electrolytes for longer workouts.
Periodize your training: after an intense cycle, be sure to include a recovery week. Progress happens during rest, not during training.
Record your workouts, nutrition and sleep quality. After a month, you will have data showing what works best.
Pain is not a sign of weakness — it is a signal. Learn to distinguish good muscle fatigue from injury risk.
Set short-term, achievable goals. Every small win builds motivation for bigger challenges.
Whatever your sport or record — proper nutrition and supplements help you achieve more. Choose the ones that suit you best:
