Breathe Easy is a workout designed to help you increase your VO2 Max and improve your aerobic capacity without spending hours running outside or pounding a treadmill. Relax your stomach and diaphragm and fill your lungs to capacity with each breath. Feel them stretching to the very bottom as you inhale. Stop inhaling only when they are filled with air to the max. Then hold each breath as instructed. Exhale slowly, when instructed, aiming to empty your lungs fully each time. This will make you feel better but it will also make you aerobically fitter.
