At Julie's Italian Ices, Hoagies & Subs (508 N. Dixie Hwy., Lantana, 561-586-2030), the specialty is the last on the list -- submarine sandwiches. A 12-inch sub, sliced meats garnished with your choice of cheese, onions, sweet peppers, jalapeño peppers, pickles, lettuce, tomatoes, and assorted condiments, weighs as much as a small dumbbell. Which means that you get a workout just lifting the thing to your mouth. But if all that strain sounds just a little too heavy for a humid summer day, check out the lightest thing in the house -- the eight-ounce homemade Italian ice. Julie's makes a total of 30 and offers about 5 choices daily, so after your biceps get exercised, your palate can cross-train.
