Women's Supportive Sports Bras Finding the best sports bra to support you is never easy but it couldn't be more important. A well fitted and supportive sports bra will reduce your chest's movement during a workout and minimise any impact to your breasts; making for a comfortable and pain free training session. This means that choosing the right sports bra for your workout is integral to protecting your breasts when exercising. A good sports bra should also help to keep your girls stay perky; this is because any physical exercise will put your Coopers Ligaments (a thin tissue that is integral in supporting your breasts' structure) under great strain. Without the right sports bra supporting you, you could cause permanent damage to your breasts and their perkiness. Check out our sports bra sizing guide for more info.
