KnockerLocker sports bras for women

Supporting your sporting ambition

KnockerLocker was set up by Rachel Ballantyne. Our purpose is to knock down one of the most significant barriers to activity- sports bras for women.

More than 50% of women suffer from breast pain. This is most commonly associated with wearing inappropriate or poorly fitting bras. More than 80% of women still wear the wrong bra size.

There is now a raft of brilliant sports bras for women available. However, many still do not wear one for working out. Shopping for sports bras for women remains problematic. Read more about why you should wear a sports bra.

We look more than ever to online shopping. But, who has time to peruse all the different sites for the best deals? To buy a variety of sizes, makes and styles of sports bras for women? Only to return 90% of them?

KnockerLocker aims to bring you the top rated sports bras for women. Alongside sound fitting and sizing advice (see our UK bra size calculator). Our new Power Rating gives advice on support levels. We include free returns with all orders.

Our goal is to increase the hits and reduce the misses. Enabling more women will be equipped to tap into the joys of sport, whatever that is for them.

Sports bras for women

Shopping with us is a positive choice. You can always find your favourite sports bra for women somewhere on line on sale. BUT we ask that you buy into our brand ethos.

KnockerLocker is about the power of female friendship, women helping women and uniting through the medium of sport.

We are stronger together. We are partnering with the Pink Ribbon Foundation, donating from the company coffers with every one of your sports bra purchases. We offer you the option to do the same through your own donation.

Every 10 minutes a woman in the UK is diagnosed with breast cancer. It claims the lives of around 12 000 women each year. This is something none of us can ignore.

Through our returns process we are supporting the work of Smalls for All. This charity provides underwear for women and children in need in Africa and the UK. Read more about Smalls For All.

Our team captain

I am Rachel Ballantyne, founder of KnockerLocker. By day I am a veterinary doctor and mum to 9-year-old twin girls. When I clock off, I am a Les Mills Body Pump and RPM instructor, dog walker and compulsive buyer of sports kit.

The power of exercise is in how it makes you feel: strong, energetic, euphoric, invincible… and those feelings come no matter the level you are working at- whether it is your first spin class, or you are a professional triathlete. I want every woman to have access to those feelings.

My very best adult friendships have been forged in a gym, on a bike or hanging from monkey bars wondering if I have one (more) pull up in me. You will see a lot of my buddies around the site- my KnockerRockers. Sport has the power to bring women together, helping push each other a bit further, to keep going when they want to quit. It unites them in their achievements and in that feel good buzz when it is cool down time. As Serena Williams says ‘We are strongest when we cheer each other on!’

However, even with the best intentions, there is nothing that will stop you faster in your tracks than a knocker shocker- a poor fitting, unsupportive sports bra for women. Through KnockerLocker I want to remove this age-old barrier, ensuring easy access to the right foundations for your sports kit.

Because every sport should be accessible to every woman.
