Restorative flow is a contemplative practice that uses props like chairs, blocks, straps, sandbags, bolsters, and blankets to totally support the body, enabling the release of mind and body tension.
It is a slow-paced practice that works to release deep tension passively, without active stretch. It is a powerful practice and can help a student to restore the body back to its normal flexibility and mobility.
The practice was developed by B.K.S. Iyengar in order to help people with injuries or illnesses, enabling them to experience the profound healing benefits of yoga without placing their bodies under too much. Iyengar encouraged the use of props and modified asanas to allow the body to relax into poses. Restorative yoga doesn’t do force. It’s about releasing, surrendering and compassion toward ourselves.
Although some particular exercises are commonly categorized as "low", "moderate" or "high" intensity, what really distinguishes them from each other is their effect on your heart rate and the overall effort that they require on your part.
One way to determine whether an exercise is low, moderate or high intensity is to use the rate of perceived exertion, which measures how difficult the exercise feels to you while you are doing it. To measure perceived exertion, observe your breathing patterns and other outward effects, like sweating.
