Cardio Respiratory training increases the effectiveness and efficiency of the circulatory (heart, blood, arteries and veins) and respiratory (lungs) systems to supply oxygen to skeletal muscles during sustained physical activity (such as a 45 minute group session).
Why is this good?
The harder and more often you train, the sooner these adaptations will take place. A good indicator of how hard you are training is the ‘Talk Test’.
Can you carry on a conversation with your exercise partner?
Yes ->Moderate intensity exercise
Can you only talk in short phrases, or not at all?
Yes ->High intensity exercise
