Sports grounds (terrain de sport) with parallel and chin-up bars

Hi to all.

I want to find some sports grounds in Toulouse where it possible to do sport. I want to find grounds where I could find parallel bars and horizontal bars/chin-up bars (I want to do parallel and horizontal bar routines). I could not find free sports grounds with parallel/vertical bars (I do not like to do physical exercises inside building).

Could you please advise me some sports grounds, which are very close to metro stations Faculté de Pharmacie, Université-Paul-Sabatier, Rangueil? If not, could you please advise me any other sports grounds?

Thank you for advance
