An active student injured his knee playing basketball and has been advised by his doctor to avoid impact activities that cause heavy force on his bones. What is the most effective activity he can do to maintain his stamina without further injury?
a. Basketball
b. Jogging
c. Swimming
d. Jumping rope
The best one would be swimming because if his doctor told him to stay off of his knee, then the others wouldn't be an option because they go against what his doctor says.
