You can use the massage ball at any time when you feel muscle tension or stiffness. Its compact size makes it convenient for quick sessions. During the day, it can be helpful for relieving tightness that builds up from prolonged sitting, such as in your upper back, shoulders, or glutes. Simply lean against it on a wall or chair for a few minutes. After walking, training, or physical activity, rolling it under your calves or feet can be part of a post-exercise recovery routine to help stimulate circulation and address specific tight spots. Using it in the evening may also help your muscles relax before sleep. There's no single correct time; integrate it into your routine based on when your body feels most restricted. It is not a substitute for professional medical advice or treatment, but a practical tool for managing everyday muscle discomfort.
