3. Strengthening weak shoulders and arms
One of the first poses you’ll discover in yoga class is called Urdhva Hastasana. It literally translates to “raised hands pose”. It’s not hard to do, but it helps to make your shoulders and arms strong.
Be sure to take your time with this pose. Find a good position, place your feet shoulder-width apart, lift your arms overhead, stay that way for some time, then start to make slopes backward and forward. When you feel tension in the shoulders, put your hands down and relax. Then go to the next pose with your hands overhead. It can be either the Warrior or Utkatasana.
4. Preventing lower back pain
The reason for lower back pain is more often hidden in spinal structure changes. Due to age or a sedentary lifestyle, the vertebrae become more fragile and less movable. Intervertebral discs (which are supposed to work as a cushion between vertebrae) dry out.
As a result, nerves, which are rooted to the spinal cord (there are 31 pairs), and are in charge of movement and of sending signals from the body to the brain, can be sandwiched between vertebrae.
Raising your hands and stretching upward can also help to avoid lower back pain.
