If you are working on overhead pressing or jerks, you need flexibility of the thoracic spine and shoulders. Attempting these lifts without full range of movement is asking for injury.
In the video below I will go over three exercises to help you increase range of motion in your spine and shoulders. Most of you will benefit from these mobility and stretching drills, especially if you sit in front of a computer or behind a steering wheel for too many hours in the day. This pattern begins in kindergarten when we start sitting for many hours, and it leads to us living slumped in chronic flexion. This causes flexion in the thoracic spine (t-spine), shoulders, and lumbar spine in teens and adults.
