Practically speaking, when we are stiff in our hips and hamstrings our knees and ankles are ‘punished’. At some stage it is better to be accountable/aware of how to work with our hamstrings and hips so that the knees and ankles are able to get on with their work. It’s also the case in twisting poses that people twist into the flexible areas of their spine and in doing so completely miss the area that needs to be ‘accountable’: we are slipping around a stiffness and there will be consequences.
Our yoga classes for children have been running for 4 years and some of the feedback we get from parents and also teachers is amazing and encouraging. Children experience stress for lots of different reasons and yoga helps them to 'discharge' it through physical movements and also through breathing exercises and meditation.
