What to look for in a sports bra

While I often opt for pullover bras, Thomas suggests wearing a clasped bra for optimum fit as you can tailor the length of the band. Plus, many women find them much more accessible. “They’re so much easier to get on and off. I always see memes on social media about how getting a sweaty sports bra off is the hardest part of the workout. Being able to loosen the back makes it easier,” she laughs.

What’s happening up top is also important – yet overlooked. “When I was testing, we’d constantly be measuring the downward motion of the boobs. But when you exercise, your boobs can move 15cm in each direction, so I was confused as to why nobody was putting support in place to reduce upward motion too,” Thomas explains.

“Rather than squishing boobs in with tight material, it’s best to restrict the range of motion that your boobs are allowed to move through,” Thomas says. She began cutting and stitching belts onto the top section of her sports bras to turn “a good running bra into a perfect running bra”. That led her to add Overband Technology to her designs for Maaree – leading to a sellout success last year.

There are so many activewear brands out there, so finding the perfect bra is usually a battle of trial and error. For medium and low-impact training, you might be OK without a fully measured and clasped bra, but I’ve realised that it’s not OK to ignore the wobble during high-knees. Wearing the right-sized bra is an obvious, but game-changing, step to better workouts.
