Bonne posture: In French, this doesn’t just refer to someone who sits up straight, but also someone who’s in a good position relative to a certain situation.

As seen in: « Le Parti québécois (PQ) est en bonne posture au terme de dix jours de campagne électorale, si l’on en croit les sondages publiés dans La Presse et Le Devoir, vendredi matin. »

(Translation: “The Parti québécois (PQ) is in a good position after 10 days of the election campaign, if we believe the surveys published in La Presse and Le Devoir Friday morning.”
