Stand with your right side facing a wall and come into a half kneeling position as close to the wall as possible, with your left leg elevated. Your torso should be upright, with your right arm extended out in front of you against the wall and your palm facing outwards. Bring your left arm to meet it, palms together. This is your start position. Proceed to slide the left hand forward, lengthening through the shoulder joint. Keeping the arm straight and maintaining contact with the wall, slowly bring the left arm overhead and round, following the hand with your eyes until you finish back in the start position with your palms touching. Repeat for the recommended amount of time (or reps) before changing to the other side.
