So! HIIT (High Intensity Interval Training) is all the
rage. I would call it outrageous.
I just returned from the 2014 IDEA World Fitness
Convention, full of motivation and ready to continue helping my clients towards
better health and fitness. And one thing is for sure: HIIT will not have any
place in my programming.
I took two classes; one with a ViPR, the other one with a
new machine called CoreStix. Ultimately, the type of device is irrelevant, but
the style of training is.
HIIT has made the headlines because it ‘burns more
calories’ in a shorter period of time, and, in today’s environment, who would
not want a shortcut. The premise is that one does one or a series of exercises
for a short period of time as fast as possible to exhaustion, then rest, and
repeat. Perfect form, we are told, is actually detrimental because in real life
we do not align our bodies in the correct way and move 100 % correct. (And I
can see that argument – to a point.)
What I have seen in my two sessions was the following: a
room full of fitness professionals all of whom without a doubt in complete
knowledge on how to perform exercises well, being cheered on by the presenter
and by motivating music to give it their all. And give it they did. As exhaustion
set in, form was lost. However, the amount of resistance remained the same. In
the heat of the moment, it was not easy to quickly find suitable modifications
to make the exercises more appropriate. Fortunately, I have reached a stage in
my life where I can leave my ego safely in the coat check and only do what
feels right, no matter how much somebody may shout “Faster, faster”.
My conclusion: fast tempo coupled with resistance is a
recipe for injury. It does not matter whether it is called Tabata, HIIT or
CrossFit.
