From an appearance viewpoint, a well built man without a muscular chest is like a lion without his mane and strength-wise, having big and strong chest muscles will give you a lot of pushing power so it’s quite useful. If something ever falls onto you while you’re lying down, you will quickly realize how useful it is to have a strong chest so don’t neglect it.
One of the best ways to build a strong muscular chest is to perform the bench press on a regular basis. Just make sure the bar is parallel to your chest when you lift because if it’s parallel to your shoulders the strain on your chest would be reduced and thrown onto the shoulder, and you don’t want that if your aim is strengthening the chest.

The problem is that people who hate going to gyms and don’t have the money or space at home to buy one cannot perform it. And even if you buy one you would not be able to perform the exercise at its best without a partner, so yes it can be problematic, which is why I recommend this exercise:
