Warm-ups:
Warm ups are highly recommended, 5 to 10 minutes is plenty.

Upper spine thorax flex inhale
while pushing your chest forward, exhale while pushing your back behind you. Same sitting posture but the hands are on knees.
Torso twists:
hands on shoulders, nose moves with head, inhale left, exhale right, twist about waist.Shoulder shrugs:
Hands on knees, shoulders raised up toward ears with inhale and allowed to relax and drop down with exhale.
Neck rolls:
Hands on knees, inhale with head straight, exhale, inhale then as you exhale let your head drop forward so your chin touches your chest. As slowly as you can, rotate your head to the right. Inhale in the back & exhale in the front. Loosen up, about 7 rotations. Then, switch directions when you come to the front. Still inhale in the back, exhale in the front. Rotate to the left for the same number of rotations.
