• Train stronger respiratory muscles to increase oxygen with every breath to increase your training endurance.
• Get lower cardio and respiratory rates plus increased lung capacity let you train at a higher intensity for longer periods.
• You'll gain stronger core body muscles for deeper, better breathing with better breath management for competition and dynamic balance
• Train your Inhale and Exhale muscles in the same breath using patented independently adjustable and interchangeable Resistance Cells. Never limits you to training inhale only or exhale only
