Women's Medium Support Adjustable Sports Bra - Black

The Fitness Cardio Training Sports Bra 520 is ideal for doing moderate-impact* cardio fitness activities (cardio boxing, fitness dance, step). This wireless sports bra has a wide, soft elasticated underband and removable foam padding. The muscle back features technical, ventilated fabric for moisture management. The technical design means you can wear this sports bra on its own. *Reduces impacts by 44.2% compared to a regular bra when doing moderate-impact activities

Your breasts, which are delicate and supported mainly by the skin, face much more impact during sports activities compared to everyday activities. No matter your cup size or age, your breasts are subject to movements and bouncing that can create a force of up to five times their actual weight. A sports bra offers the support and comfort you need for your fitness activities. A sports bra can help protect your breasts from impacts, pain and premature sagging.

The movements of sports activities stretch the skin and ligaments. Without sufficient support, you may end up with pain or premature sagging. However, too much support can also be detrimental in the long term: the support level must be perfectly suited to your bust size and the impact intensity. The aim is to protect your bust without altering natural breast movement.

We designed our sports bras with three different levels of support based on the activity: light support for activities that create little bust movement (eg, Pilates, stretching, strength training), medium support for activities that involve moderate, non-repetitive movements (eg, fitness dance, cardio training), and high support for activities with intense movement (eg, step, treadmill running, trampoline).

A sports bra that fits properly provides better support and comfort. To choose the right size, use a tape measure to determine your bust circumference (while not wearing a bra): Stand in front of a mirror, Hold the tape measure horizontally around your upper back, at the base of your shoulder blades, Bring the tape measure across the fullest part of your bust, Without pulling it tight, take the measurement, Check the size guide to find your size.

DOMYOS sports bras are designed by our teams to optimise your comfort and prevent health problems. We do not use underwiring to prevent injury and compression of the lymph nodes, we use minimal seams around the nipples to prevent chafing, and we opt for components that promote moisture management to keep you comfortable and reduce the risks of irritation.

All our models are verified in our labs using our bust support test, which measures the decrease in acceleration of the breasts during sports*. The models are tested and ranked from 1 to 5: 1 for light support, 3 for medium support and 5 for high support. *DOMYOS fitness sports bras guarantee slowed acceleration of bust movements by at least 10% (level 1) and up to 50% (level 5) compared to a classic bra.

Yes, of course! All our fabrics must successfully pass rigorous lab tests to ensure your comfort and safety. We test them for colourfastness, resistance to repeated washing, perspiration wicking and more. We call these our "torture tests". And after that? Sports users like you test the products while doing their sports activities. We listen to and analyse their feedback to fix what needs to be improved to finalise the product.

The environmental impact of every product is calculated for its entire life cycle using various indicators. An overall A/B/C/D/E rating is indicated on the product so you can easily identify the most eco-friendly products. We compare products from the same categories to determine each product's rating. Decathlon is a voluntary participant in this environmental labelling initiative. For more information: http://sustainability.decathlon.com/
