The Saudi government is expressing the same concerns as the Princess, as the country is now among nations with the highest prevalence of obesity. Saudi Arabia’s 2030 Vision, published in 2016, aims to get 40 percent of the population more active by 2030. That plan may include the licensing of women-only gyms.

Princess Sara doesn’t know yet how exactly NuYu will fit into that vision, but she expects to continue keeping Saudi women active. That goes for women both older and younger than its average age of 25-35.
