Exertion One (X-1) high-performance clothing is engineered specifically for the athlete — designed to enhance performance, maximize comfort, and provide fashionable style that slims and accentuates. X-1 fitness apparel optimizes the conditioning cycle, from initial warm-up and training right down to the cool-down. X-1 workout apparel maintains and stabilizes body temperature during low- and high-intensity activity, provides support for your core muscle groups, helps the body stabilize and return to its resting state, and reduces muscle fatigue, providing essential support throughout the training and post-training cycle. X-1’s fashion-forward workout apparel is both comfortable and chic for the modern athlete in us all.
