High Intensity Interval Training (HIIT) classes are fast 30 minute metabolic workouts using a combination of bodyweight only exercises working big muscle groups at high intensity intervals that will set your metabolic rate through the roof!! A short period of working to the MAX creates a metabolic effect in the body and sends your post workout recovery into overdrive, ultimately burning more fat! If it feels easy, you ain’t working hard enough!
“I am so delighted that Central Health Physiotherapy introduced me to HIIT. After knee surgery these sessions quickly got me back to fitness and helped shift the few extra pounds that I added whilst injured. I am now evangelical about HIIT. As a time poor professional I love the high intensity of these sessions; they really pack a punch! It has had a much greater impact on my health and fitness than running or any of the other exercises and sports that I do!” Lewis Cohen, Lawyer
The Objectives of HIIT Classes
In a nutshell:
- Improve your metabolic rate
- Maximize fat loss and improve fitness
- Improve strength in all body groups
- Do the above in the shortest possible time
These workouts aim to increase Resting Metabolic Rate (which accounts for the largest proportion of your energy used in a day). The HIIT exercises incorporate many muscles groups, through all planes of movement and the intensity is near maximum hear rate. This leads to an increase in EPOC (Excess Post-exercise Oxygen Consumption is the repayment of oxygen debt built up during exercise). The higher the EPOC, the harder the body has to work to return the body to resting state, burning more calories in the process. After sustained, low intensity exercise half of the total EPOC is paid back in 30 seconds and total recovery can be made in a few minutes. With High Intensity Interval Training blood lactate is increased, it may take 24 hours to re-establish pre-exercise oxygen uptake. During this time your resting metabolic rate and calorie burning is increased!
HIIT Class Structure
Following a warm up to increase range of motion and muscle activation the main HIIT session (12 – 20 minutes) comprises set periods of work with set periods of rest.
