Last week I helped Men's Health magazine on a piece about getting
workouts done fast. Personally, I think you can get a great body-
changing workout done in minutes.
How fast?
I'm talking 10-minutes.
By now, I'm sure you're asking...
How do you lose fat in only ten minutes?
or
What about the rule that it takes 20 minutes of cardio before you
start burning fat?
Well, first of all, as I have said before, the whole idea of a fat-
burning zone or a magical fat-burning time period just doesn't fit
with the common sense approach to fat loss.
People can lose fat without doing any cardio at all - so its clear
that you don't have to workout for at least 20-minutes with your
heart rate at 60% of your maximum heart rate. Fat loss is far simpler
than that - and I'll show you some basic workouts below that crank
your metabolism and help you burn calories when you are not
exercising.
Second, the results of your training occur outside of the gym rather
than during the workout. That's why the before-mentioned "increased
metabolism" is so important. If you put the right "turbulence" on
your muscles in 10-minutes, you can change your body - without even
thinking about doing cardio....
