**thing puts your antiperspirant to the test like spinning for two hours straight or twerking out to a marathon of Beyoncé hits. That's exactly the life our panel of fitness Instructors live on the daily. We polled women who make Their living working up a sweat to find out which stench-stoppers actually work.
From barre Instructors to cardio pros, these ladies have a knack for looking unfazed - even after the fifth set of squats - and these are the deodorants they trust. We promise these products can stand up to sweat-soaked sports bras and won't reveal white residue while you're doing jumping jacks. Each antiperspirant ahead is gym-bag approved (and a few are aluminum-free formulas).
