You've curled dumbbells, Zumba'd, and cycled on a stationary bike to booming reggaeton. But have you ever done a workout for your mental fitness? We're not talking crossword puzzles and Sudoku to keep your thinking sharp. We're talking emotional well-being and happiness.

Turns out that just as we aren't born with rock-hard abs and a fast 5K time—that's where exercise comes in—happiness isn't innate either. With a little intention and a bit of time set aside each day, we can practice being happy and train our way to better moods. Use the Greatist Happiness Tune-Up to get started getting happier.
