Which technique is least likely to be appropriate for someone with a herniated disc?

High-impact aerobic exercises are least likely to be appropriate for someone with a herniated disc due to the significant strain and force they place on the spine. Such activities can exacerbate pain and potentially worsen the condition, leading to increased discomfort and risk of injury.

In contrast, gentle stretching, controlled strengthening, and Pilates rehabilitation exercises are generally more beneficial for individuals with a herniated disc as they focus on improving flexibility, stabilizing the core muscles, and providing low-impact movements that can enhance spinal health without undue stress. These approaches aim to promote healing and restore functional movement, making them suitable options for rehabilitation and support.
