Fish Pose traditionally dictates that your legs be in a full lotus. Here, you simply bend your knees and cross your legs while lying on your back. Slide your right hand under your right buttock, left hand under left buttock. Tuck your forearms and elbows close to your torso. Pressing through the elbows, lift your torso and head up from the floor.The weight is on your elbows, allowing you to gently lower the crown of your head to the floor. This is a pose to learn in a yoga class; however, you can gain strength just by pressing into your elbows and lifting and opening your torso in the first part of the pose, without worrying about needing to drop your head back, especially if your neck is tight. Breathe here for half a minute. On exhale, lower your torso to the floor.
