1 Did you know breasts can bounce up to 15cm in any direction if you’re not wearing the right sports bra? Getting enough support is important because otherwise the delicate ligaments of the breast can stretch, exacerbating any natural sagging, and unfortunately the damage is irreversible. At M&S, there are two levels of support available in our Goodmove sports bra range: medium support for activities ranging from yoga to hiking and ultimate support for exercise such as running or HIIT.

2 If you have larger breasts, always opt for high or extra-high-impact support, as your bust will naturally move more and therefore needs extra hold.

3 When buying a sports bra, always buy the same size as your normal bra. It may feel firmer, but this is because it’s designed to minimise bounce. However, it should still feel comfortable and allow complete freedom of movement – if in doubt, mimic the activity you are planning to do in the bra when you try it on.

4 A cross-back sports bra is a good idea if you want extra support and hold for the bust. The cross-back design provides excellent support during physical activity, minimizing breast movement.

5 Sweat can deteriorate fabrics if not washed out, so pop your sports bras in the washing machine after each wear. All M&S bras are tested for durability, so they can withstand multiple washes. As sports bras are vital to support and protect the breast tissue, it’s a good idea to replace yours every year to ensure you’re getting the optimum performance from your bra.

6 Look for breathable fabrics to help you stay cool and comfortable when your exercise. Goodmove bras feature moisture-wicking fabric to draw sweat away from the body allowing it to evaporate more quickly. We also use lightweight fabrics and meshes in certain areas that require more ventilation. Check out The Sports Edit for fashion-forward sports bras to get you noticed at the gym.
