Nerves tighten your grip and shorten your breathing, and that's what turns soft dinks into pop-ups. A long exhale slows your heart rate, so every session starts with breaths that are longer out than in.

You'll set aside what you can't control, pick three things to do on every point, and picture both your best rallies and the hard moments, so a bad call or a run of misses feels familiar when it comes.

Use the pre-match reset before you play, the short one at a side switch or between bracket matches, and the long one in bed the night before a tournament. Headphones help at a busy court.
