Countless workouts have been cut short due to the friction burns caused by skin rubbing on skin (especially if it also involves razor stubble like in your pits or bikini area—ouch!). Protection is the best defense, Dr. Lawson says: "Choose smooth, low-friction fabrics to limit chafing." She adds that if you are large chested, "there is often more contact/rubbing between the breasts themselves than the rest of the body" so an "encapsulation" type sports bra that separates each breast into it's own cup can help. Other friction-less options include compression gear, body lubricants like Body Glide, and making sure your clothing is appropriate and well-fitted (i.e. wear running tights instead of shorts if you typically get thigh rub).
