sometimes we hold a lot of our tension in our body and muscles. Shaking out a few of those kinks and curves in your body may make dealing with the kinks and curves life throws you a little easier.
When doing any exercise (even 'relaxation' exercises), don't push yourself too hard. After all, that's not relaxing! And, always use correct posture, move slowly and cautiously, and get the most from each exercise.
stretch your neck, stand or sit up straight, get some of the tension out of your body.
