Studies further show the most effective training is threshold resistance as opposed to a flow depletion method. You may notice improvement within several days. Both inspiratory and expiratory muscles are trained by breathing in and out with regulated resistance. Oxygenating the body provides more than seventy-five trillion cells with oxygen needed to carry out brain, muscle and organ function. When consistently applied one can begin to detect a difference in a few days and experience improved lung function in a few weeks.
Benefits are improved breathing strength, endurance and technique.
