All you need to start exercising is a wall!
The neck and head
Stand against a wall and press your back into it, starting from your lower spine. Press your tailbone into the wall first, then curve your upper back, so that it doesn’t touch the wall. Slowly roll your back over the wall. Bend your neck forward and stretch the top of your head toward the ceiling as if a string were pulling you upward. Don’t bring your chin too close to your collar bone. You should feel a slight stretch in the neck during this exercise.
