Yoga props and yoga without injuries
Sustainable practice
Sustainable means that you want to be able to continue doing yoga without injuries. More often than not, people get injured doing Yoga because they forgot to maintain a good posture foundation.
Some people do more importance to breathing than how a posture (exercise) is performed. In reality, both are equally important; nonetheless, a good foundation will prevent injuries and if we want to maintain our practice through time, this is the way.
Tim Senesi has a good foundation series in his website but you may access for free his beginner guide series at YouTube.
