CrossFit, a privately owned company founded in 2000 and headquartered in the U.S., offers wellness and fitness services. Employing approximately 1650 people, the organization focuses on promoting and organizing CrossFit fitness programs, events, and competitions.
CrossFit established movement requirements, nutritional guidelines, and intensity targets based on safety, efficacy, and efficiency. CrossFit participated in the diet debate, advocating a low-carb, low-calorie, good-fat approach, contrasting with the then-prevalent low-fat, low-calorie, high-carb diet. The popularity of the Concept2 SkiErg increased among CrossFit, HYROX, and functional fitness communities. The rise of functional fitness classes, including CrossFit and HYROX, fueled the demand for cross-training shoes, leading brands like Nike and Puma to produce shoes suitable for both lifting and running.
