@vitalfeng: Can you hold this for 5 minutes? This is Wall Horse Stance, an ancient Chinese training move. Lean your back flat against the wall. Knees above ankles, thighs parallel to the floor. Core tight, chest up. No knee over toes! Build strong legs, boost stamina, fix weak knees. No equipment needed. Do it at home. #WellnessTips #taichi #qigong #health #exercise #fitness
