quadruped position pushing floor with hands to protract scapulae, then returning to neutral
Get down on hands and knee position i.e on 4 points ( both hands and both knees), hands under the shoulder and knees under the hip. Push the floor using the hands rounding the shoulders, release the push to back to starting position and repeat.
Nothing here is a prescription. Your physiotherapist decides which of these are yours, and when.
