No, you don't need to be a gymnast for this exercise. If you have a large stability ball, you can use that. If not, something as simple as a rolled-up blanket or towel will work. If using a stability ball, roll yourself into a backbend, placing your hands on the wall behind you for support, or the floor if you are quite flexible. Keep your shoulders down and focus on lengthening the neck.
If you don't have a stability ball, or don't feel up to the challenge, roll a blanket or towel up and position yourself on the floor, lying on your back with this support just below your shoulder blades, arms straight out from the shoulders, resting on the floor.
