A common reason for muscle cramps during exercise is dehydration or an imbalance of electrolytes in the body. When engaging in intense physical activity, the body loses fluids and electrolytes, which can lead to muscle fatigue and spasms. Insufficient stretching or overexerting muscles during exercise can also contribute to cramps. To mitigate this, it is vital to maintain proper hydration and replenish electrolytes, such as sodium, potassium, and magnesium, particularly in hot or humid conditions. Awareness of one’s physical limits and appropriate warm-up routines can also reduce the frequency of muscle cramps.
