Annie Thorisdottir is a 2x CrossFit Games champion and a legend in the sport of CrossFit. She has over 10 Games appearances, became the first woman to win back-to-back titles, and placed third at the Games in 2021, landing on the podium only a year after giving birth to her daughter Freyja.

When you think of ‘high performance’, it’s synonymous with everything Annie Thorisdottir stands for. Her ability to balance her career and family while being a high achiever is a representation of our ethos at Momentous. We’re beyond thrilled to partner with Annie and have her be an extension of our brand.
“I am very excited that I signed with Momentous. The reason I partnered with them is not only does Momentous have some of the best supplements on the market but there is actual research behind them. There is reasoning behind why they make the blends that they make.”
