The Mobilizer for back flexibility
Flexibility is a key component of fitness. Flexibility includes joint mobility and is a key factor especially when dealing with the middle back which can tend to be stiff due to the attachment of the ribs to the spine. This simple middle back exercise is an excellent way to gain better flexibility in the spine. Due to the rotation, side bend and extension pattern, it increases mobility in the vertebral joints and promotes better posture. The concept is basic; keep the joints mobile as well as the stretching the muscles. This video highlights the details.
