When a person experiences bonking, which is a term commonly used to describe a state of severe fatigue or energy depletion during prolonged physical activity, they often encounter symptoms such as light-headedness and weakness. This condition typically occurs when glycogen stores in the muscles are depleted, resulting in a drop in blood sugar levels. The brain and body become starved of fuel, leading to a significant decline in physical and mental performance.

Light-headedness can manifest as dizziness or a feeling of faintness, making it difficult for the individual to maintain their physical activity or even stand upright. Alongside light-headedness, weakness occurs because the muscles do not have enough energy to continue functioning effectively. Individuals may feel shaky or fatigued, which indicates a critical need for rest and nutrition to restore their energy levels.

Understanding the dynamics of bonking is essential for personal trainers as it helps them to educate clients about the importance of proper nutrition and energy management during workouts. This knowledge allows trainers to develop appropriate training regimens and nutrition strategies to prevent such occurrences, ensuring clients can perform optimally and safely.
