I have been getting cramps in my calf muscles.
People can get cramps in their calf muscles due to a few reasons.
The first might be a failure to stretch adequately before and after exercising. Muscle cramps might also develop from simple overexertion, a case of pushing yourself too far, too fast. The third possibility is an insufficient intake of fluids. Staying hydrated is essential to keeping your electrolytes in balance, and allowing your muscles to contract and relax. The balance of electrolytes in the body, i.e. sodium, potassium, chloride, calcium, phosphorus, magnesium, and carbon dioxide rely on adequate levels of hydration.
