You can also use ankle weights. I use 1 lb wrist weights and I have the 1 lb gloves that can also be 1/2 lb ones, but I've actually benefited the most from my adjustable 5 lb weights as they allow me to go at 1/2 lb increments and being able to use them at 3 lbs and 4 lbs has been what's gotten me up to the next 5 lbs for things that need dumbbells over 15 lbs. Chest flys and one arm rows especially come to mind.
