Which of the following is the best reason to rest muscle groups between workouts?
a. it allows the muscles to store more energy.
b. it allows you to focus on other muscle groups.
c. it allows the muscles time to heal.
d. it allows the muscles to properly overload.

The answer to the question is c. it allows the muscles time to heal. Anytime one does a workout, muscle fiber is damaged from the intensity of the workout. It is therefore wise to switch to another muscle group for the next workout. If one continuously works out the same muscle groups without giving them time to rest, they are at risk for damaging the muscles.
