Assalaamualaikum sheikh, Is it permissible to go to gym if there is a women’s only section and a mixed section meaning in the mixed section there won’t be many women, also sheikh why is the mixing of genders of the gym different to the mixing of genders in the market?

Ustadh AbdulAziz al-Haqqan
Isn't it self evident? Any place of fitnah your should avoid as the fitnah there is intense. The market u go to buy something and go back.
