Benefits: A perfect end-of-workout and anti-aging position. Has the same healthy, stress-reducing effect as hanging upside down in inversion boots, bathing the thyroid gland and the brain in blood and oxygen, helping to clear lactic acid and lymphatic-waste buildup, increasing the metabolism, and strengthening the immune system.
