Part of the "new normal" for many people is working remotely from home. Swapping your normal office desk for a kitchen counter, sofa and end table, or kitchen table can result in uncomfortable neck and back pain because you are not maintaining proper posture.
Part of the problem with sitting in a slouched position or one where you are leaning over and your back is in a "C" shape, causes your muscles and tendons in the neck, upper back, and mid-back to become stretched, tight and elongated.
When sitting and working for prolonged periods, it can cause all sorts of aches and pains in the neck and back. To avoid unwanted pain, use these simple stretches every few hours.
You don't have to know how to do Yoga or be an expert at fitness and exercising either! The objective is to focus the movements on targeted areas to help loosen them up and reduce pain and discomfort, while also helping to strengthen these areas.
