HIIT training is a useful tool for most individuals trying to achieve any transformational fitness goal. So what exactly is HIIT? Simply, it means you will work at high intensity (such as sprinting/jog on a treadmill, stationary bike, rowing machine etc) followed by an interval of low-intensity exercise (such as walking at a slow pace) or complete rest.
Some of the key benefits of HIIT are:
- Excess post-exercise oxygen consumption - Described as an increase in the rate of oxygen uptake which is designed to erase the oxygen debt after a period of strenuous activity or exercise.
- Burns Fat - Proven to have a greater increase in specific hormones that increase fat oxidisation and speeds up metabolism.
- Continues to burn fat well after your training session has completed - Your muscles will utilise more carbohydrates for up to 36hrs after high-intensity interval training, therefore less likely to store as body fat.
- Stimulates growth in your muscle fibres - High-Intensity Interval Training helps create new mitochondria which recruit larger muscle fibres responsible for using more fat as energy and helps metabolise food better.
- Enhance Muscle Hypertrophy/Growth - Increase in muscle will increase the consumption of calories 24hrs a day.
Based on the benefits listed above; you can see that HIIT is perfect if you are trying to lose fat and gain muscle, as it promotes fat loss and muscle growth simultaneously. Individuals pursuing general fat loss goals would also benefit from HIIT.
