Prone thoracic extension is designed to activate your thoracic spinal extensors, leading to improved posture and preventing a forward slumped position. This is important for decreasing stress on your spine and preventing compression fractures.
Begin by lying on your mat face down. You may place a pillow under your hips if this position is uncomfortable in your lower back region. Place your hands out to the side with your elbows bent to 90 degree angles.
Gently lift your collar bone off the floor. Hold this position for 5 seconds. You can work your way up to 10 seconds as this exercise becomes easier for you. Lower back down to the starting position.
