Answer:
The time of day
Step-by-step explanation:
Although there are many important factors that need to be taken into account when planning and executing an exercise program, for you or another person, the least important factor to take into account is the time of day in which it is decided to perform the planned exercises.
Although, it is still extremely important to take time for sleep, so it is not a problem to perform an exercise program at night, however it should not affect your sleep patterns.
