No, I'm not suggesting you sink all of your money into
every fat loss product imaginable. In fact, you can go
into this kind of debt without spending a nickel. I'm
talking about oxygen debt, and it is critical to fast and
efficient fat loss!
Traditional "cardio", where you do long bouts (45 minutes
or more) on a treadmill or an elliptical machine at a
moderate pace has always been the recommendation of doctors
and trainers. Why? Because at a moderate pace your body
is using stored body fat for energy. You'll often see this
referred to as the "fat burning zone." So, why is burning
body fat a bad thing? Have I finally lost my mind?
Your body is a pretty complicated engine, so when the fat
is being burned, it says "well, I better save up some fat
for the next time we go through this." So, what does it
do? It uses your lean muscle tissue to help preserve fat.
Now, that doesn't sound right, does it?
Confused? It's really quite easy. You don't exercise to
see the results that happen to your body during exercise -
all of the magic actually happens after, not during,
exercise. So, while you rest and recover, your body is
burning the fat. Yeah, baby!
Intervals, which are short bursts of exercise followed by
recovery, don't use fat as their energy source. During
interval training, your body will call on carbohydrates
which are stored in your muscles. The effort that your
body needs to go through to replace the carbohydrates
stored in your muscle is much more intense, therefore it
needs to call on the stored body fat for up to 24 hours
after you're done. So, you would rather burn fat for 45
minutes or 24 hours?
Back to oxygen debt - this is how you can judge the proper
intensity of your interval training. Simply put, your
interval needs to be of a high enough intensity that, when
you stop and start recovery, that you are left panting.
This means that your body is asking for more oxygen than
you currently can provide.
You can also monitor yourself with a heart rate monitor.
If your interval was intense, your heart rate will actually
bump up when you stop before heading downward.
In 20 minutes or less, you'll be revving up your fat
burning engine like never before. At some point I'l share
some of my favorite interval workouts with you. But for
now, even if you're just walking outside, crank up your
intensity for 30 seconds, followed by 60 seconds of
recovery at a slower pace for 20 minutes total.
