Saudi Arabia is planning to open its first women-only gyms to aid with weight loss, although they will still be banned from competitive sports such as volleyball, basketball and football.
The change in policy was announced by Princess Reema bint Bandar, who is vice president of women's affairs.
This follows the first ever women's day in the Kingdom.
She told Arab News: 'It is not my role to convince the society, but my role is limited to opening the doors for our girls to live a healthy lifestyle away from diseases that result from obesity and lack of movement.'
Any Saudi women hoping the emulate the Williams sisters are also facing disappointment as tennis is also still on the banned list.
Women will be permitted to go swimming, running or bodybuilding - as long as there are no men present.
According to the new policy, the gyms must focus on improving fitness and encouraging weight loss.
Bandar wants female entrepreneurs to invest in the new facilities which are known as 'micro businesses'.
