Deep stretching involves being assisted into a particular pose for an extended period of time, typically 30 seconds to several minutes, while focusing on deep breathing and relaxation. The poses are often designed to target specific muscles or areas of the body, such as the hips, hamstrings, or shoulders, and may involve the use of props such as blocks, straps, or blankets to support the body and deepen the stretch. The goal of deep stretching is to improve flexibility, range of motion, and overall mobility, while also promoting relaxation and stress relief.
