Of the 11 subjects who dropped out of the training program, two cited time concerns with the remaining nine subjects (16% of total recruited subjects) citing overuse or injury for failing to complete the program and finish follow up testing.”

What is “overuse or injury”? The study does not define what it means by the term “overuse.” The study also does not detail what specific cases of “overuse or injury” the subjects cited, what caused them, whether the cases were pre-existing… Continue Reading

As a child, Annie Thorisdottir took ballet. It didn’t stick for long, though. Like her cousins, she wanted to try gymnastics. She made it to Iceland’s national team but quit to focus on high-school studies.

“Going from training 24 hours a week into training not at all didn’t really work out for me,” the 23-year-old two-time CrossFit Games champion says with her quintessential smile.

So she started ballet again, and dance. That, too… Continue Reading

“We both woke up from the OR with a… Continue Reading
