Half Kneeling Thoracic Rotations
To do Half Kneeling Thoracic Rotations, set up in a half-kneeling position on the ground with both hands on the ground inside your front foot. Palms should be flat on the ground. If you are less flexible, you may need to come up a bit on your fingers as you rotate.
Then lift one hand and rotate your chest toward the front leg. Keep your front foot flat on the ground as you do it. Reach up and rotate your chest toward that front leg. Place the hand back down on the ground and then lift your other hand up toward the ceiling and rotate your chest away from the front leg. Really reach open and don’t let your front foot rock open.
You can even keep that arm against the leg to help you rotate. Place the hand back down and repeat the rotation toward your front leg. Move slowly and keep your front foot flat on the ground.
