Breathing Exercises for CrossFit
Breathe through the WOD — don't let the WOD breathe you
CrossFit creates a unique respiratory challenge: constantly varied movements at high intensity with minimal rest. The metabolic demands shift between aerobic and anaerobic multiple times within a single WOD. Athletes who can't regulate their breathing between movements accumulate oxygen debt that crashes their performance in the final rounds. The fittest athletes aren't always the strongest — they're often the best breathers.
During WODs: the breathing hierarchy is (1) mechanical — exhale on exertion for every movement (exhale on the press, pull, or push phase). (2) Recovery — during any transition (walking to the bar, chalking hands, resting at the top of a movement), take 3-5 extended exhale breaths. These micro-recoveries compound across a WOD. (3) Pacing — if you can't maintain rhythmic breathing, you're going too fast. The breathing breaks down before performance does — it's an early warning system.
Between WODs (competition) or between strength and metcon: 3-5 minutes of structured recovery breathing. Extended exhale (inhale 4, exhale 8) for the first 2 minutes, then coherence breathing (inhale 5, exhale 5) for the remaining time. This accelerates the parasympathetic shift and reduces the heart rate faster than passive rest. The athlete who recovers fastest between events has a compounding advantage across a multi-event competition.

Frequently Asked Questions
How quickly do breathing exercises produce results?
Acute effects (reduced heart rate, calmer state) begin within 60-90 seconds of starting. Chronic benefits (lower baseline anxiety, improved HRV, better stress resilience) typically emerge after 2-4 weeks of consistent daily practice. The research shows that 5 minutes daily is the minimum effective dose for long-term benefits.
Do I need any equipment or apps?
No. Breathing exercises require only your lungs and a timer. While apps and devices can be helpful for learning, they're not necessary. A free online timer (like this one) provides visual pacing and audio cues that guide you through any technique. Once you've learned the patterns, you can practice anywhere without any tools.
What's the best breathing exercise for beginners?
Box breathing (inhale 4, hold 4, exhale 4, hold 4) is the most recommended starting technique because it's simple to remember, produces balanced autonomic effects, and works for virtually any situation — stress relief, focus, sleep preparation, or performance. Start with 5 minutes daily and expand from there.
