This man brought a book to read at the gym
As with everything in life, there are people who like to exercise and people who do not. Although working out is still important to stay healthy, even those who hate it should go to the gym every once in a while.
This man clearly belongs to the group that hates working out, but he still paid for a membership, so he thought he might as well use it. That is why he brought a book along and laid down on a weight bench to read a nice book.
