Prep your body before exercise by applying anti-chafing sticks, balms, or creams to the areas of your body that are most prone to friction, such as your inner thighs, underarms, nipples, or bra line. These products help create a protective barrier that reduces skin-on-skin or fabric-on-skin rubbing, says Lal.
“These anti-chafing sticks and creams repel sweat and water. They keep skin dry and allow the skin to slide over itself, again decreasing friction,” he says. You can also use these tools if you plan on exercising in wet weather, so that the rain will “bounce off” the skin instead of seeping into it, he adds.
Look for fragrance-free, sweat-resistant formulas designed for athletes, and reapply the product as needed during long workouts, especially in hot or humid conditions, says Lal. You could also try layering a bit of petroleum jelly on top of sensitive areas, dusting anti-chafing powder into your shoes, or using antiperspirant to prevent sweat and armpit chafing, he adds.
