Students of GCSE Science will look at the requirements of staying healthy. This is the second of six quizzes on that topic and it looks in particular at the effect that exercise has on our health.
Eating a balanced diet is an important factor in staying healthy, but so is exercise which has a positive effect on our health in many ways. During exercise your body's metabolic rate increases which means you burn more calories. Exercise also builds muscle mass. The metabolic rate of muscle cells is greater than that of other cells even at rest. Exercise therefore helps your body to control its weight more easily.
