Combine warm water, yeast, and sugar in a bowl. Let sit until foamy, about 5 minutes.

In a large mixing bowl, combine salt, olive oil, and 2 cups of flour. Add the proofed yeast mixture and stir until combined.

Gradually add the remaining flour, mixing until a sticky dough forms. Knead until smooth, about 5 minutes.

Shape the dough into a ball, spray with cooking spray, and cover. Let rise in a warm place until doubled in size, about 1-2 hours.
