At the very foundation of any serious training kit is the humble yet essential t-shirt, and this is where Under Armour truly excels.

The Cornerstone of Your Workout: Under Armour T-Shirts

An Under Armour t-shirt is more than just a piece of clothing; it´s a critical piece of performance equipment designed to manage moisture, regulate temperature, and provide complete freedom of movement. Forget the distraction of heavy, sweat-soaked cotton. Our collection of Under Armour fitness t-shirts at traininn is built to keep you focused on your form, your reps, and your goals.

Discover the innovative technology that sets these training tops apart. The iconic UA Tech™ fabric offers an incredibly soft, more natural feel for ultimate comfort, but with all the performance benefits you demand. Its superior Moisture Transport System wicks sweat away from your body, pulling it to the surface of the fabric where it can evaporate faster, keeping you drier and lighter throughout your session.

For workouts that generate serious heat, the legendary HeatGear® line is your ultimate ally. These lightweight t-shirts act like a second skin, delivering exceptional breathability and ventilation to keep you cool when the pressure is on. Whether you prefer a Compression fit to support your muscles and improve blood flow, a streamlined Fitted cut that moves with you without constriction, or a generous Loose fit for maximum comfort and range of motion, there is a HeatGear t-shirt engineered for your training style.

Push the boundaries of performance with advanced fabrications like Iso-Chill, which actively helps disperse body heat, making the material feel cool to the touch for unparalleled comfort during the most intense workouts. For those seeking to maximize their output, UA RUSH™ technology features a mineral-infused fabric that absorbs the energy your body emits and reflects it back into your tissues and muscles, improving endurance and strength.

Every detail is considered. With features like 4-way stretch construction for unrestricted mobility in every direction, anti-odor technology to prevent the growth of odor-causing microbes, and strategically placed mesh panels for added ventilation, an Under Armour t-shirt is built for the grind. Equip yourself for success in the gym, on the track, or in the studio.
