What technique involves tensing and relaxing major muscle groups?

The technique that involves tensing and relaxing major muscle groups is progressive relaxation. This method is designed to help individuals focus on the differences between muscle tension and relaxation. By systematically tensing and then relaxing specific muscle groups, a person can cultivate a greater awareness of physical sensations and reduce overall physical tension and stress.

Progressive relaxation is often used as a stress management tool, aiding in the reduction of anxiety and promoting a sense of calm. This technique encourages individuals to consciously engage with their body, which can have both mental and physical health benefits. It differs from other techniques such as meditation and visualization, which focus primarily on mental processes rather than physical muscle control and relaxation.
