Is CrossFit 3 times a week enough?

Yes. For most people, CrossFit three times a week is enough to build real strength, conditioning, and body composition. Three quality coached sessions with recovery days between them drive steady progress and are far more sustainable long term than five rushed or fatigued workouts.

This is a direct answer from the CrossFit BC coaching team. Short version first, then the detail and the local context for training in Vancouver. If you want the same answer applied to your own situation, a coach will walk through it with you in person.
