POWERbreathe CLASSIC SPORTS PERFORMANCE (Heavy Resistance)

POWERbreathe uses the basic principles of resistance training. Just as you might use weights to strengthen your arm muscles, breathing in through POWERbreathe against the heavy, variable resistance makes your breathing muscles work harder - thereby increasing their strength and endurance.

Within a few days of using this drug-free, easy-to-use hand-held device, your breathing muscles will feel stronger; within 3-weeks you’ll feel less breathless; and within 4 weeks activities, exercise and sports will feel easier.
