Chop up apple, celery, cucumber, and ginger into easily blendable pieces (keep the skin on these ingredients, yes, even the ginger!).
Add chopped ingredients into the blender.
Add lemon juice, handful of spinach + big splash of water.
Blend on high for up to 1 minute or until ingredients are very well blended.
Pour blended juice over a fine mesh strainer into a large sealable glass container. Use a soft spatula to press the pulp against the mesh strainer to help get as much liquid through the strainer as possible.
