Question

why do we get muscle cramps after heavy exercises​

Answer 1

Explanation:

Muscle cramps occur when there is anaerobic respiration taking place in our muscles. During anaerobic respiration, glucose gets converted into lactic acid which leads to lack of oxygen. A hot water bath or a massage can help in getting relief from the muscle cramps.
