Half boat exercise is one of the challenging yoga poses for “sitting bones” as you have to balance your whole weight on your sitting bones. This pose works to tone and strengthen abs, obliques and core muscles too. It is essential to use a yoga mat to keep your bones from hard floor during the pose. Core abdominal muscles support your spine and posture and it is important to strengthen them with proper moves. Half boat exercise provides you an opportunity to work for your core abdominal muscles in order to support your whole body posture and build your muscles.
