Why you should do High Intensity Interval Training.


Hi there, welcome back to Jim’s Sports and Fitness blog.  

Today I wanted to talk about Cardio fitness, and High Intensity Interval Training in particular.  On a regular occurrence I will work with people who have been visiting the gym for several months without seeing much progress before they come to me as a Personal Trainer.  They will have been focusing on using different weights and machines and building muscle.  Obviously I am a huge fan of muscle building, but it’s incredibly important to maintain Cardio exercises alongside muscle building.  And my favourite way to do this is by incorporating HIIT into training schedules.

High Intensity Interval Training (HIIT) is a technique that can be incorporated into many different workouts.  It describes basically any workout which involves short bursts of intense activity followed by periods of less intense activities.  You can follow the HIIT technique for most types of workout, for example you can use it for muscle building.  However it is more commonly used for Cardio.  

One of the best benefits about High Intensity Interval Training is that it is highly efficient.  A ten minute cardio workout using HIIT can burn more calories than a continual 30 minute workout on a treadmill.  Recently the American College of Sports Medicine found that 2 weeks of HIIT workouts can be more productive than 6 – 8 weeks of regular endurance training.

Due to the fast speed of HIIT your heart rate should peak at a higher pace,  This means that you will also burn more fat and calories for a longer period of time when doing HIIT work outs.  These longer periods of fat burning are perfect for anyone who likes to combine Cardio with weight training.  Ad even better unlike other conventional forms of Cardio, HIIT won’t encourage muscle loss, instead you lose fat not muscle.
