In tennis you execute a lot of upper body rotations, and if your muscles and spine are flexible, you can load and unload better and have more powerful shots. Every tennis player can benefit from twisting and stretching their spine; and with better flexibility, you are reducing the risk of injuries as well. If you sit a lot during your day and feel low back pain frequently, stretching your spine with twists will relax your back muscles and ease the pain. Often we stretch our spines forward and backward but it is also important for them to be twisted laterally. This twisting in different direction than they are used to helps to better relieve the tension. This side twisting rhythmic and gentle motion limbers the muscles, aligns the vertebrae, boosts the blood circulations, loosens the hips, and even chest and shoulder muscles.
