9 Deodorants Workout Instructors Pack in Their Gym Bags

The expert: Mandi Molnar, Head Trainer at DavidBartonGym's Christopher Street location
The deodorant: Dove Dry Spray Antiperspirant ($7)
Why she loves it: For a fitness instructor, once a day isn't enough for deodorant application. Mandi likes to use this spray formula when it's time for a touch-up between classes because it doesn't leave white clumps when applied to sweaty pits.
