Description

BreathBooster Breathing ExerciserThe BreathBooster is a highly effective inspiratory muscle trainer, providing an easy and convenient means of increasing the strength and durability of the respiratory muscles. It works on the principle of resistance. As you inhale, the resistance created makes your respiratory muscles work harder. The harder they work the stronger and more durable they become. As your breathing power improves, the BreathBooster can be gradually adjusted to provide more resistance. Just a few minutes of training a day can help.
