I’m sure that many people, especially students, constantly
make up excuses to not go to the gym or to exercise because they don’t have
time. I know from my own personal experience, I have skipped a gym session or
two because I had to write a last minute paper or had some sort of assignment
to complete.

Cardio workouts usually involve long and constant effort
(depending on how they are performed). Scientists believe cardio activities can
improve your cognitive ability to carry out multiple tasks for long periods of
times.
On the other hand, strength/resistance training requires
a great deal of focus to maintain proper form. You must also concentrate on
your breathing, and tune out others around you, while maintaining a steady pace
and time, depending on your fitness goals. Researchers believe that the more
you perform focused resistance training exercises, the more you will be able to
avoid distractions in other areas of your life. As such, exercise is helpful
for students (like me) when having to write papers, especially when on a
deadline, as their brain activity would function faster.
