Often, terrain conditions do not allow you to lie down freely on the ground and shoot at the target. You have to crouch or stand, holding your air rifle.
There are several rules for using a forced kneeling position. First, your right knee touches the ground, and you rest the air rifle on the other. Additionally, there are several different versions of the rifle grip, whether it is a spring or a PCP rifle.
Remember to breathe properly and aim at the target. You will see more in my video. I invite you to my movie. Enjoy
