Congratulations
You could also set a fitness goal such as
training for a sprint triathlon
training for and running a 5k
working up to swim a mile
take lessons to learn a new sport such as golf or tennis
learn how to salsa
take pilates private classes with a teacher (great for core)
learn how to ride a horse
waterski
downhill ski
ride the bike cross-country -- or plan a b&b trip with the bike
It's even more fun to try new things as a reward for the new body especially if it is something active -- it can really boost the motivation.
