PowerLung® has been proven to increase endurance and performance by training the muscles you use to breathe. Although running increases lung capacity, most runners don't breath deeply enough to use all the their available lung capacity. PowerLung® trains the muscles used to bring air into and out of the lungs and studies on performance athletes showed as much as a 30% improvement in lung muscle strength and endurance with the type of training PowerLung® offers. Each model is independently adjustable for inhale and exhale training in the same breath. Excellent for non-athletes and the elderly (where no medical conditions preclude this type of training) to the highest level athletes. Complete instructions are included with each model.
The PowerLung® Sport is for athletes who desire to move their training program and performance to the next higher level. This model provides a serious workout that starts at a higher level of resistance. The lowest level of resistance for this model is the highest level on the Trainer model.
