September is the time to come back to everyday routine, also the sports one. After the holidays, it is time to get back to your passion and favourite activities. Today we will discuss coming back to the gym and fitness classes. Gym or fitness outfit isn’t only about comfort and functionality, it’s also a way to feel self-confident and enjoy physical activities. Properly matched design, fit, and colours can add energy, motivate to exercise and make every training a small routine. For many of us sport isn’t just an obligation but it’s a passion and lifestyle, so it’s good to choose an outfit that will reflect our attitude and support us in achieving goals. We suggest how to dress for the gym and fitness classes to exercise effectively, comfortably and with a smile on your face.

Why is the right training outfit so important?
The right outfit for a weight training or fitness class is an absolute must. Why? Because it directly affects your safety, comfort and exercise performance. Clothing made from stretchy, breathable materials helps to avoid overheating, excessive sweating and discomfort that could distract you during your workout. Equally important is the right fit - well-fitting clothing provides the full range of movement so needed for dynamic fitness classes, relaxed yoga or intense weight training.
Shoes are an equally important part of a sports outfit. They are the foundation of the entire workout, absorbing shocks, stabilising the body and protecting the joints. The right footwear minimises the risk of injury - from minor ankle injuries to knee strain to more serious back problems. During strength training, well-fitting shoes support correct posture and balance, which is of great importance when lifting weights. For fitness or cardio classes, they provide a dynamic bump and flexibility for lighter movements and better use of energy.
So when choosing your outfit for the gym or fitness classes, remember that clothing supports your comfort, but footwear creates a solid foundation on which to build your athletic goals.

How to dress for a fitness class? 3 trendy looks for your workout
Fitness classes are quite dynamic, so a comfortable outfit that allows a full range of movement is a must have. What should you wear?
- loose-fitting tops and T-shirts in technical fabrics that wick away moisture and keep your skin dry,
- leggings,
- bikers for summer training.
It is also fashionable to choose sports outfits that are not only functional but also fashionable. The Adidas by Stella McCartney brand supports women who are always on the move, which is why you will find fashionable and functional sets for different types of exercise. We've put together three fitness outfits that prove that fashion and sport don't have to be mutually exclusive.

Sporty set with an animal print
Animal prints are going to be particularly trendy this season. So why not bring them to the training room too and add a bit of edgy flair? In the Adidas by Stella McCartney collection you will find a sports set designed for intense training. It's not just functional - the leggings with AEROREADY technology wick away moisture effectively, keeping you dry and comfortable even during the most demanding workouts. What's particularly eye-catching? The striking animal print, of course, which fits perfectly with the new season's trends. Sportswear can also be a statement of self-confidence. Sports kits with animal motifs are the ideal choice for women who want to train to the rhythm of fashion and feel good in every movement.

Energetic set for intensive training
Dopamine dressing is a trend that has also entered the training rooms. Intense colours can act as a natural mood booster, adding energy and making every movement lighter and more dynamic. Colours have the power to stimulate action, something that Adidas by Stella McCartney uses perfectly in its collections. The brand boldly opts for juicy, characterful shades that perfectly combine fashion with functionality.
For fitness, the leggings made of a durable material that wicks away moisture and provides comfort even during the most intensive workouts. The elastic waistband additionally shapes your silhouette, emphasising your assets and supporting you in every movement. You can match the set with a top in the same energetic yellow shade - light, breathable and designed for complete freedom. This is a set that not only fulfils its sporty role, but also makes you enter the training room with a smile, confidence and a lot of good energy.

In the trendy colour of the season
The latest colour combinations feature purple in a refined version. Why not bring it into the training room too? Falke has done it in style. The purple top with seamless construction minimises the risk of irritation and the wide shoulder straps distribute the weight appropriately. This will make your workout extremely comfortable. Match with a pair of purple leggings with a high polyamide content, which wick away moisture quickly to keep your skin dry. This combination is sure to get you noticed in the training room and make you the queen of sports fashion.

How do you dress for weight training?
Gym clothes should be made of lightweight, breathable functional materials such as polyester with elastane or polyamide with lycra. It's worth noting that materials that are too thick will not work well for weight training, as they can result in poorer performance and a shorter workout. With the right materials, you'll be able to maintain adequate thermal comfort during your workout. Avoid clothes that are too tight, as they restrict your movements and can cause chafing. Clothes that are too loose won't do the job either, as they can make it difficult to exercise. So how should you dress for the gym? We have 3 suggestions for you.
Minimalist classics in black
Black for the gym is always a good choice. It is timeless, practical and elegant. The ⅞" leggings from Adidas by Stella McCartney accentuate your silhouette for added confidence, while their length further stabilises your figure and keeps you comfortable while you move. The fitted top with flat seams will keep you comfortable even during intense workouts, thanks to its seamless construction that minimises the risk of chafing.

In fashionable shades of brown
For fans of minimalist fashion combinations, a sports set in the most fashionable shades of brown is ideal. The brown sports bra has a minimal amount of seams, allowing you full freedom of movement and comfort when exercising. For consistency, you can choose leggings in the same shade to go with it, which guarantee a perfect fit and support in the waist area. Their added appeal is their versatility - they are perfect not only for the gym, but also for athleisure styling.

Energetic look in pink
This look is a nod to the timeless pink that will get you in the mood at the gym and energised. The pink leggings are a great way to enhance your silhouette and still be comfortable. Match them with a sports top in the same shade for stability during dynamic exercises. This monochrome set is not only practical, but also fashionable. You can wear it every day with a white oversize shirt. We love these versatile combinations, which you can also use after a workout, over coffee with a friend.

Which shoes for the gym and which for fitness classes?
Gym shoes are an important part of your workout gear. They should provide support on the heel and sides of the foot. This will help you maintain stability when performing exercises such as squats or various types of pull-ups. A flat, stable sole will pass the test. If you are planning a dynamic workout, choose footwear with lightweight cushioning that absorbs shock.
Shoes for fitness classes should be suitable for active training. They should provide adequate support at the heel and arch of the foot. In addition, they should absorb shock during jumps and lunges. When choosing sports shoes for fitness classes, also pay attention to the midsole - it should provide good stability, which will help you maintain your balance. Also remember that the footwear should have good grip on different surfaces. Fitness shoes should also be made of breathable materials to keep your foot dry during your workout.

Fashionable and functional accessories for training
Outfit is key, but well-chosen accessories can take your workout to the next level - both in terms of comfort and style. We've put together a list of what to bring to your fitness class so you feel prepared and motivated:
- A stylish sports bag - practical, roomy and fashionable at the same time. Great not only at the gym, but also on your way to work or a meeting.
- Bidon or water bottle - preferably reusable, designer and thermal. Staying hydrated is essential for any workout.
- Sports towel - lightweight, quick-drying and in fashionable colours. Essential for intense exercise.
- Exercise mat - ideal for yoga, Pilates or stretch classes. Choose one that is non-slip and has an interesting design.
- A headband or rubber band - an inconspicuous but extremely practical accessory that makes it easier to focus on exercise.
- Smartwatch or sports band - for those who like to monitor their progress and motivate themselves with results.
- Wireless headphones - ideal for solo workouts when you want to get into your rhythm and exercise to your favourite music.
