Plus Size Gym Wear

From t-shirts and leggings to supportive sports bras, our plus size collection contains a range of classic pieces for your favourite activities. Whether you're engaging in yoga, cardio, or hiking, it's advisable to opt for layers, allowing you to regulate your temperature as your activity warms you up. Look for natural or breathable fibres, which help to draw away moisture and keep you feeling fresh. Decathlon works with partner brands to offer you a wider choice. Now that your gym wear basics are sorted, take a look at our range of plus size coats and comfortable, high-tech gym trainers.
