We love the ease of a protein shake, how long we feel satisfied and the way it curbs our cravings. But when you’re on the go or traveling, it’s not always easy — especially when you don’t have access to a blender. That’s why our current obsession is blender bottle shakes. They are so easy to make and take when you’re on the go, even on a vacay or a work trip. Plus, no blender clean-up, which is a bonus in our book.
