The answer is letter A.
Overused injuries are a result of excessive
activities and the lack of appropriate rest and healing. When a person
continuously performs active aerobics for a long period of time and does not
observe the importance of rest, the body will trigger a response and would lead
to injuries. Injuries need the time to heal by way of resting, which many
overlook when they are too engrossed in their physical activities. The best way
is to exercise and rest on alternating days, this way the body will have ample
time to recover and heal from the previous activities performed.
