Questions & Answers about Vous garderez une bonne posture à condition de vous échauffer.
Why do we use à condition de here instead of à condition que?
We use à condition de followed by an infinitive (vous échauffer) because the subject of both actions is the same (vous). If the subjects were different, you would use à condition que followed by the subjunctive mood. For example: Vous garderez une bonne posture à condition qu'il s'échauffe (You will maintain a good posture provided he warms up).
Why is it vous échauffer and not s'échauffer since the verb is in the infinitive?
Even when a reflexive verb is left in its infinitive form, the reflexive pronoun must still agree with the logical subject performing the action. Since the person doing the warming up is vous, the pronoun changes to match, making it vous échauffer.
Could I use pourvu que to mean 'provided that' in this sentence?
Not in this exact structure. Pourvu que (provided that or as long as) must always be followed by a conjugated verb in the subjunctive. It does not have an equivalent de + infinitive form like à condition does. To use it here, you would have to conjugate the second verb: pourvu que vous vous échauffiez.
Why is garderez in the simple future tense?
