Silk, America’s No. 1 plant-based beverage brand, is celebrating the release of its new high-protein beverage Silk ULTRA by giving fitness enthusiasts the chance to win the gym gear they need to keep crushing the game – from the convenience of their home. Introducing the Silk ULTRA Upgrade, which will arm athletes with hard-to-get equipment such as kettlebells, free weights, resistance bands, and an ample supply of Silk ULTRA to take them through the year. But for a chance to upgrade, they must unleash their inner beast mode by completing one of two 10-minute, high-intensity ULTRA Sweat Sessions, hosted by decorated athletes Michael Phelps and Aly Raisman.
