Dumbbell - Use an incline bench and perform the same actions as the video suggests.
Cable Shoulder Press - Stand or sit and adjust the cable handle to hip level or lower. You can do as shown in the GIF below or bring the hands into the chest and lift from there to mimic the exercise in the tutorial.
Fixed barbell press - You don't have to add the squat, but you can if you like. If you choose not to squat, start the exercise by kneeling, then starting from the chest, press the bar up. If you're shorter, you may not need to kneel.
