Final answer:
For safe workout routines, it is recommended to perform a maximum of three sessions targeting the same muscle group in one week, allowing at least 48 hours of rest between sessions for muscle recovery. So the correct option is B.
Step-by-step explanation:
When it comes to performing workout activities targeting specific muscle groups, it is generally recommended to allow those muscles at least 48 hours of rest to recover. This rest period helps prevent overtraining and promotes muscle recovery and growth. Therefore, the maximum number of sessions that can be safely performed for the same muscle group in one week is typically three. This recommendation ensures that you are not exercising the same muscle group on consecutive days, which could lead to insufficient recovery and increase the risk of injury.
