This exercise is perfect for opening the chest and improving spinal rotation. 

How to do it:

1. Sit up straight in your chair, feet flat on the floor.

2. Place your right hand on the back of your chair and gently twist your torso to the right, using your left hand for support.

3. Hold for 15-30 seconds, then switch sides.

Benefits: The seated torso twist not only helps with spinal mobility but also promotes better digestion and relieves tension in the core.
