How to Train Your Respiratory Muscles

The Spyro Tiger P100 is a device that allows you to rebreathe your own CO2. It's really the only two devices on the market that allow you to train the strength of your respiratory muscles. The hard start training interval would be something like 125 meters at a 141 pace, a 144 pace, a 149 something a little higher. By slowing down across that interval, you're going to be able to sustain a high percent of peak O2 consumption and a high percentage of your V02 peak.
