It's essential to wear a sports bra when taking part in any type of sport or exercise. A good fitting sports bra will be supportive holding the bust firmly and spread the weight of the bust onto the shoulders and back preventing painful movement and long-term tissue damage causing the bust to sag.

Impact Levels

Sports bras are generally categorised by impact level the highest rating is impact level 4 or Extreme. This means it's suitable for running, football, tennis, horse riding etc. Even if you have a small bust you still need a bra suitable for your activity. Medium impact level three is suitable for running etc if you are cup size A or B and impact level 2 is suitable for general gym wear, yoga, pilates, cycling, weight training etc. Please see the impact level chart below for a rough guide to workout which impact level you require for your chosen activity.
