Pushups are great, but don't just do pushups - you definitely want to integrate pull-ups to get a balance between chest & back. If your chest muscles are overdeveloped relative to your back, you are exacerbating the bad computer posture of shoulders rolled forward and forward head posture known as upper crossed syndrome.

For 99% of people here just push-ups will be much better than nothing, it's much harder to find a pull up bar than do push-ups. You won't get overdeveloped muscle just from push-ups.

A good exercise to pair with push ups is horizontal rows. They're easier than pull ups and don't require a pull up bar. I do them with a sturdy wooden broom handle between the back of 2 chairs.

you can also do them underneath an (office) desk, by holding on to the edge and pulling yourself up from the floor
