Jayne Cherrington-CookHow to choose a sports bra: Finding your perfect fit
Did you know breasts can bounce up to 15cm in any direction without the right sports bra? Without enough support, the delicate ligaments can overstretch, contributing to long-term sagging that can’t be reversed.
When considering how to choose sports bras, start with impact level. Low-impact styles work well for yoga or Pilates, while medium/high activities such as cycling, running or HIIT need firmer support.
Design also matters. Compression styles press the breasts close to the body and suit smaller busts or gentler workouts, while encapsulation bras support each breast individually and are often among the best sports bras for fuller cups.
For the best fit, measure snugly under the bust and across the fullest part of the chest, then move around to check comfort and support. A sports bra should feel secure, but never restrictive. You can also book a bra fitting with us for extra help.
Get comfort and style with Goodmove sports bras
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.
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.
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.
The best sports bras for bigger breasts
When shopping for the best sports bras for bigger breasts, support should always come first. Larger busts naturally move more, so high-impact styles are essential, even for activities that feel relatively low key. Look for bras with wider, cushioned straps to help distribute weight comfortably and reduce pressure on the shoulders, alongside a firm underband that anchors everything in place.
Structured cups are key, too. Encapsulation styles that support each breast individually tend to offer better control and shape than softer compression designs alone, with wired sports bras offering even greater support and separation.
A well-designed sports bra should feel secure from the first wear, without digging in or restricting movement. Adjustable straps and multiple hook-and-eye fastenings allow for a more personalised fit, which can make all the difference to comfort, confidence and long-term support during exercise.
The best sports bras for small breasts
The best sports bra for small breasts balances support with comfort, offering a secure feel without unnecessary bulk. Compression styles are a great choice, holding the bust close to the body to reduce movement while maintaining a natural shape.
Look for soft, supportive fabrics and a firm underband that keeps everything in place. While smaller busts may not need heavy structure, a well-fitting sports bra should still feel stable, comfortable and confidence-boosting from the first wear.
Non-wired designs suit smaller cup sizes beautifully, providing a smooth, flexible fit that moves with you. You could even choose a vest top with added light support for yoga, Pilates or stretching sessions. Light padding can also be useful, adding subtle shape and coverage without compromising breathability.
