Final answer:
It is true that the body will change and grow stronger as you exercise, through processes of muscle hypertrophy and bone strengthening.
Step-by-step explanation:
The statement "The body will change and grow stronger as you exercise" is true. When you engage in physical exercise, particularly if it involves weight-bearing activities or resistance training, you initiate a process of muscle hypertrophy, where structural proteins are added to muscle fibers, increasing their diameter.
This process enhances muscle size and strength. Conversely, if muscles are not used, they can atrophy and decrease in mass and strength. Similarly, bones are dynamic and can modify their thickness in response to changes in muscle strength or body weight, strengthening as a result of regular exercise. It's also worth noting that exercise can help to slow down the age-related deterioration of the body.
