There is no scientific evidence to suggest that different races have inherently different levels of fitness genes. Fitness is influenced by a combination of genetic factors, lifestyle choices, and environmental factors. While certain genetic variations may be more common in specific populations, fitness levels are highly individual and can be improved through regular exercise, proper nutrition, and healthy lifestyle habits regardless of race. It is important to focus on overall health and well-being rather than attributing fitness levels to race. **
