Anníe Mist Þórisdóttir (given as Annie Thorisdottir in international media) is a professional CrossFit athlete from Reykjavík, Iceland.

[8] She is 170 cm (5 ft 7 in) tall, weighs approximately 67 kg (148 lb), and hopes to go into the medical field.

[11] On the final day of competition, an event called "The Chipper"[12] was announced that included ring muscle-ups.

She attempted the muscle-up many times unsuccessfully before finally getting one rep in front of the cheering crowds.

She earned a DNF on the event, and dropped in the overall standings to 11th, but made herself known as a contender for the title of "Fittest on Earth."

In 2013, Anníe was not able to defend her title due to a back injury (a herniated disc)[7] sustained while too casually lifting heavy weight.

In her first live competitive appearance since her injury, Open Announcement 14.5 in San Francisco, Anníe trailed far behind the other champions, Sam Briggs, Rich Froning, Jason Khalipa, and Graham Holmberg,[15] and received the high-fives of her competitors at the end of the workout while shaking her head in apparent disappointment.

Anníe went on to win the 2014 Europe Regional, while 2013 Games champion Sam Briggs of England failed to qualify (4th overall) due to a poor performance on the max distance handstand walk.

[20] Anníe placed first for women at the 2013 Dubai Fitness Competition, taking away more than Dh650,000 ($177,000) in prize money.

Anníe has been in a relationship with fellow CrossFit athlete Frederik Ægidius (often written as Aegidius) from Denmark since 2012.

[24] On August 11, 2020, Anníe gave birth to the couple's daughter, Freyja Mist Ægidius Frederiksdottir.

[26] On May 1st 2024, Anníe gave birth to the couple's second child, a boy named Atlas Týr Ægidius Frederiksson.
