Half-Moon pose gives quick energy and vitality; improves and strengthens every muscle in the body’s core, especially in the abdomen; increases the flexibility of the spine; corrects bad posture; promotes proper kidney function; and helps to cure enlargement of the liver and spleen. It increases the flexibility and strength of the rectus abdominus, latissmus dorsi, oblique, deltoid and trapezius muscles. Half-Moon also firms and trims the waistline, hips, abdomen, buttocks and thighs.
Remember that when you do the Half-Hoon pose your body is not warmed up yet. You might not be able to bend sideways as much as you would like, so don’t be discouraged.
Keep your leg muscles and torso as engaged as much as possible when you bend sideways.
Keep your tailbone tucked under slightly when bending backwards. You should feel a lift in the chest not just in the lower back.
