Steady - state cardiovascular training — such as a 45 - minute jog performed
at about 55 to 65 per cent of maximum heart rate — causes the body to opt for a higher percentage of fat for fuel and its
lower intensity means it can be performed over an extended

It has become the most popular fitness advice: ditch the hour - long,
low intensity cardio for a 20 minute high
intensity interval training (HIIT) workout in which you alternate short
periods — from 30 to 60 seconds
at maximum
intensity follow by the same duration or longer the recovery
period.
Burning calories
at low intensity for long
periods of time activates fat rather than burning glucose, so it will slowly chip away

lower -
intensity recovery
periods — builds cardiovascular strength and stamina.
While steady - state (
low to moderate) forms of cardio can and should be performed for extended
periods of time to see maintenance and improvements in VO2max (think upwards of 45 minutes
at a jog), HIIT training for cardio fitness involves working
at an
intensity that can only be maintained for about 20 to 25 minutes.
