The TrainingMask® will give you a substantial edge in your workouts. The TrainingMask® is a tool that is designed to improve your conditioning, strength, and power. Oftentimes the only thing that separates someone who is really fit from someone who is getting in shape is how much work they can do and tolerate during an exercise session. If you can do more work and sustain that work load longer, you will be that much closer to fitness or athletic excellence. TrainingMask® can give you the stamina, endurance, and workout capacity you need to stay the course and get results.
