Like many of my friends, I am constantly busy with my academic work.
Until last year, I would usually manage to play some soccer or other sports
with my friends during lunch or after class. However, this year, my studies
have consumed most of my time, leaving little room for physical activity.

Recently, I’ve noticed that I become out of breath even when walking up the stairs. I am
wondering if there are any tips for staying healthy without giving up too much study time.
