Exercise doesn't just cause muscle soreness—many women also deal with breast discomfort during or right after workouts.

Many Women Experience Breast Pain During Exercise

Five Common Causes of Breast Pain

1. Not Wearing a Proper Sports Bra

Strong support is essential. A quality sports bra is one of the best investments for active women.

2. Your Sports Bra Is Worn Out

Elasticity fades with use and washes. Underwire styles can bend, digging into the skin painfully.

3. Chafing from Sportswear

Rubbing fabrics against breasts—especially nipples—can cause raw, painful irritation.

4. Your Menstrual Cycle

Breasts often feel tender before your period, making exercise more uncomfortable.

5. High-Intensity Workouts

Excessive breast movement during vigorous activity amplifies the pain.

The Solution

You can't always prevent breast pain entirely, but you can reduce it significantly. Prioritize a well-fitted sports bra. Here's how to choose the right one.
