Powerlung is the original and only respiratory strength training apparatus with integrated exhale and inhale adjustable resistance, for strength and conditioning. 

Breathing presents an unexpected opportunity for biohacking that can yield substantial improvements with relatively small effort. Presently, athletes and trainers use aerobic exercise as a way to increase breath capacity. Surprisingly, research shows that aerobic exercise does little to strengthen the 12 sets of muscles involved in respiration. A breakthrough in breath training, Powerlung, now raises the cardio-pulmonary bar.

The elegantly simple handheld unit employs adjustable resistance. You can build both the strength of your inhale and exhale muscles, resulting in increased breath capacity and better endurance.

Below are the respiratory training results from studies conducted with various groups of people:

• Athletes were able to move more air with fewer breaths
• Improved endurance-performance in soccer players
• 16.7% improvement in endurance-performance of sprint athletes
• 12% improvement in walking treadmill test for elderly women
• Improved lung function in cross-country runners
