Note: If a movement causes you pain, Stop!
Back up and do the movement up to, but stopping short of, when it began to hurt.
Try some variations. Move less, smaller, or slower whatever it takes to avoid the pain.

CAUTION: If you have osteoporosis, a currently diagnosed bulging disc, spondylosis, spondylolisthesis, or spinal stenosis, please review the exercises in this book with your doctor or physical therapist before you begin.
