Considering that you don't have any fitness equipment at home. Maybe you can do it: grab the upper door frame and do pull-ups. In fact, pull-ups have a very good effect on latissimus dorsi and teres major.

If there is no way to get to the door frame, you can also consider rowing unilaterally. You need a heavy object (you can't tie it up with many thick books), and then find a bench or two stools. One hand holds the stool, one knee kneels on the stool, the other leg supports the ground, and the other hand lifts the heavy object through the contraction of latissimus dorsi until it reaches the limit, and then slowly relaxes. 8- 10 group is exhausted, then switch sides and do 5-6 groups in a row. This effect is also quite good.
