HIIT
High Intensity Interval Training
-
Increased fat metabolism.
-
Short term increase to your metabolic rate. (You’ll
burn calories after you’ve finished)
-
Increases in human growth hormones (HGH)
responsible for metabolism regulation and the ageing process.
Not only do you get these benefits when you regularly perform
HIIT but it will also make you a lot fitter. Research has shown that doing HIIT
increases muscle oxidative capacity by almost 50%, increases glycogen storage by
20% whilst improving cycle endurance capacity by 100%. The University of Nebraska found that thirty second
intervals were better for building endurance and aerobic capacity than
intervals lasting three minutes. Therefore short intense interval training is
an effective proven way to quickly build fitness.
It is tough though as you’re working above your aerobic
threshold for extended periods of time and I would not recommend it to a
complete beginner.
Example HIIT
Workout
If you want to do it in a gym then find a treadmill, bike,
cross trainer etc. and set your total time limit. If you haven’t done HIIT
before start with about 10 minutes. This total time will comprise of 30 seconds
“rest time”: 30 seconds “work” time. During your work time you need to focus on
hitting a percentage heart rate of at least 80-90% of your maximum and during
your rest time you need to focus on recovering to get ready for the next
interval. If you feel you need more time to recover in between intervals then
increase your rest time and decrease your work time slightly and vice versa.
That’s the beauty of HIIT training you can play around with the work rest ratio
until it suits you. Remember the whole point of HIIT is that you’re working
above your aerobic threshold during the work times; you should be breathless
and building up lactic acid in your muscles so don’t be afraid to work hard. You
can also do this outside following the exact same principles as above obviously
you will be limited to bodyweight exercises like running, burpees or cycling
presuming you own a bike.
I hope you can incorporate HIIT into your training programme.
Whether you’re looking to get fitter, faster or stronger it will definitely be
of benefit. Start by doing it once or twice a week at the start or at the end
of your session and if you need any more assistance or guidance please feel
free to ask a member of the gym team to show you!
