High Intensity Interval
Training: A New Frontier in Fat Loss
by Nathan Latviatis
Are you exercising for long
periods of time to try to burn fat? If you’re like most
people you probably are, but there is a better, more efficient
way. It’s called “high intensity
interval training” (HIIT) and lately it has started to become
pretty famous for its obvious health benefits.
-So, just how do you perform HIIT?
Simply put, HIIT is based around this concept: Go fast then go
slow. Repeat. You can perform HIIT routines on pretty much
any
machine you want like a treadmill, elliptical machine, cycling
machine, or apply it to almost any sport (swimming, cycling,
running).
Try to keep the bursts of speed at around 90%-100% of max
effort.
Here is a sample HIIT routine:
Sprint 20 Seconds
Rest 10 Seconds
Repeat 4-8 Times
Or
Sprint 15 Seconds
Rest 5 Seconds
Repeat 4-6 Times
These are just samples, you can change it however you want (you
could even use distance instead of time). Remember though,
HIIT is based around the concept of fast bursts of work. Also,
to continually challenge yourself and also to continually
make
progress you should increase the level of effort required. You
could add extra sprint cycles to the routine, shorten the
rest
periods, lengthen the sprint periods, try to run farther in the
set amount of time, or (if you are going for distance instead
of time),
try to complete the distance in a shorter amount of time. When
starting out on your HIIT routine, don’t kill yourself the
first time
though. You may have to work your way up, don’t be afraid to
start out at a low intensity with low sprint times and high
rest times.
-What Are the Benefits of HIIT?
--Major Increase in Fat Loss
In a study done by Tremblay and other authors, two groups were
assigned different training regimens. Group A performed the
regular moderate intensity cardio (like jogging or bicycling)
for 20 weeks and Group B performed a HIIT routine for 15 weeks.
In
the end the results of each group were recorded. Group B lost
nine times more fat than Group A and in 5 weeks less! (1)
--Increased Lactic Acid Threshold
Lactic acid is that burning sensation you feel when you work a
muscle really hard. Lactic acid is a byproduct of the
processes
your body uses to make your muscles work. When too much lactic
acid accumulates in the muscles, the muscles become
fatigued. You’re lactic acid threshold is how fast your body
can remove the lactic acid in your muscles. When your body
can remove lactic acid more efficiently, then you can work the
muscles at a higher intensity for a longer period of time
before
they become fatigued.
--Shorter Workouts
I don’t know about you, but I definitely would rather crank it
up a notch and exercise for 4-8 minutes in comparison to
staring
at the wall in the local gym for 30 minutes to an hour
jogging…or performing any other slow, and somewhat boring type
of cardio.
-So why does HIIT burn more fat than regular moderate intensity
cardio, like jogging?
To put it simply, after your HIIT training session is over with
your metabolism explodes and tons of calories are being
burned.
These calories are being burned because your body must recover
from the HIIT workout you just exposed it to (the details
as
to why exactly this happens are pretty complicated, and would
take a long time to explain, so I’ll spare you). Just
understand
that after the workout, not during the workout, is when the fat
is being burnt.
HIIT offers people an extremely effective and, as shown by the
study done by Tremblay and other authors, a very fast way
to
eliminate fat. In addition to this, it can increase your
muscle’s resistance to fatigue. Although, probably the best
part about
this type of training is that you no longer have to spend 30
minutes to an hour at your gym jogging away your life on the
treadmill.
Here's a tip: Personally, I enjoy listening to some type of
fast paced music while performing an HIIT workout. Doing this
can
really increase the intensity of your workout, and similarly,
the productivity of it as well. Some type of MP3 player
usually
works best because they don't jiggle around very much.
If you decide to take up HIIT training you may want to check it
out with your doctor first. This type of training is
incredibly
effective, but it is also very intense.
