Go Further with Every Breath
CrossFit pushes your strength, endurance, and mental resilience through constantly varied, high-intensity workouts. Just as you train your body to perform under pressure, your breathing can become an important part of your routine.
Developing better breathing habits can help you stay composed during demanding workouts, recover more efficiently between rounds, and maintain consistency from your first repetition to your last.
Whether you’re preparing for your next WOD or working toward a new personal best, training your breath can become another tool in your performance toolkit.

Key Benefits
Expand-A-Lung uses adjustable resistance to train both your inhalation and exhalation muscles similar to how weights strengthen your body. Consistent use helps improve breathing capacity, endurance, and breathing efficiency
Stronger breathing muscles can delay diaphragm fatigue during intense exercise, helping you perform longer before feeling out of breath. Ideal for runners, cyclists, swimmers, martial artists, CrossFit athletes, and other endurance sports.
Whether you’re a beginner or an experienced athlete, the resistance dial lets you start comfortably and gradually increase intensity as your respiratory muscles become stronger.
Train for just 3–5 minutes once or twice daily. Most users notice improvements in breathing endurance within 2–4 weeks of consistent use. Athletes can also use one additional set before workouts as a warm-up.
Unlike traditional breathing exercises, Expand-A-Lung provides physical resistance that challenges your breathing muscles, allowing them to become stronger over time rather than simply practicing breathing patterns.
A stronger diaphragm contributes to better core stability during heavy lifting, supports efficient breathing mechanics, and complements yoga, breathwork, and post-workout conditioning.
Compact enough for daily travel, built from durable BPA-free, latex-free silicone and high-strength materials, and designed to provide years of reliable respiratory training with proper care.
