What activities is the medium-support muscle back seamless bra suitable for?

When playing, it’s essential you feel comfortable when moving. This means that you should choose clothing that makes it easier to move and take up postures.

How does the medium-support muscle back seamless bra provide freedom of movement?

You go all out, to the point where you are often fully covered in sweat at the end of a session. This isn’t always a very pleasant feeling, right? Well, thanks to this sports bra, you can say goodbye to moisture caused by sweat. The technical fabric can wick away sweat. It also dries faster to keep you dry. 
For greater efficiency, we also added a ventilated area between the breasts.

Stay dry, even when you are pushing yourself to the limit! How is this possible with the seamless, muscle-back, medium-support bra?

The running bra has two flexible single-thickness cups (no shell).

What type of cups does this medium-support muscle back seamless bra have?

Did you know that your breasts are supported almost exclusively by your skin? This makes them vulnerable and, during physical activies, the forces exerted on them are even higher than usual. The movements and bouncing they experience can make them up to five times heavier depending on the intensity of the sport. Wearing a sports bra will give you all the support, comfort, and protection you need. You are also protecting them from impacts, pain and premature sagging.

Why must your chest be supported during sport?

During sports, breasts experience forces that stretch the skin and ligaments of the chest. Lack of proper support can cause pain and premature sagging. However, too much support can also have negative consequences. The level of support your bra provides must be tailored to your bust size and the intensity of the impacts. 
The objective:To protect your chest while preserving the natural movement of the breasts.

What are the advantages of choosing between high, medium or low support?

Our labs test the models using a bust support test that measures the reduction in breast movement acceleration during sports activities. They are evaluated and then sorted into the following three levels: 1 for low support, 3 for medium support and 5 for high support.

How are the support levels of the Decathlon sports bras tested?

Depending on the type of sport you do, the support level of your bra will vary. We offer the following three options:
- Level 1: low support for activities that require slight chest movements (pilates, stretching, muscle strengthening, etc.); 
- Level 3: medium support for activities that cause moderate bouncing (dance, fitness, cardio-training, etc.); 
- Level 5: high support for activities that involve intense movements (step, treadmill, trampoline, etc.).

What sport should you associate with what level of support?

To keep your bust supported and comfortable, the bra size that you choose must be suit your body shape. This is how you do it:
- Stand opposite a mirror with a tape measure;
- Place it horizontally at the top of your back, on the lower part of your shoulder blades;
- Hold the tape over the largest part of the bust;
- Read the measurement without pulling the tape measure tight;

How do I measure the size of my bust to choose the right sports bra?

The racer back spreads support evenly across the back. 
For D-cup and above, we have developed other, more suitable models.
