get this body today! |
Have you ever noticed
how most people will spend time on the treadmill, elliptical or stationary bike
before they hit the weights? They try to get their cardio out of the way first,
reasoning that it's the best way to be nice and warm when they finally do start
lifting.
BIG
MISTAKE! Want to make the most of your workout? Do it the other way around.
Why should you start
your workout by lifting weights? Simple: your body only has so much energy available in your muscles.
Your
body can store about 80 calories' worth of glucose in your bloodstream, while
your liver stores between 300 and 400 calories' worth. That means you have a
total of 380 to 480 calories of easy-access energy to burn in your body.

When
you start your workout--no matter whether you do cardio or strength training--your
body begins to burn glucose to provide energy to your muscles. You use your
muscles, but your lungs haven't yet begun to take in enough oxygen to keep up
with the energy burning. For the first 10 to 15
minutes, you are burning pure glucose.
Now,
what happens when you run out of glucose? Your body starts to burn
fat, but fat is much harder to burn. It takes longer
for your body to activate the fatty acids that have been stored in your body's
cells, so you get less energy than you would if you were burning
glucose.
How does this relate to the order of your workout?
Let's
say you spend 30 to 45 minutes on the treadmill and another 20 to 30 minutes
lifting weights. If you did your cardio first, you would burn up all or most of
the glucose that is floating around your bloodstream and in your liver. Your
run would activate the fat in your body, but it would be a slower burn of energy. When
you tried to lift weights, you would run out of energy a lot more quickly.
Now
let's switch it around and see what happens. During the first 30 minutes or so
of serious, high-intensity training, you burn around 500 calories. That's just over what your
body has stored, so your body will be depleted of glucose. However, when you
hit the treadmill or stationary bike to do your cardio, your body will already
have activated the fat for burning, and so you will be burning
fat almost exclusively. If you do your 30 to 45 minute cardio session AFTER
your weightlifting, it's high quality fat-burning simply because there is no
glucose left in your body to burn!
Bonus: When you lift weights, your heart rate is elevated and it
stays that way for hours after you're done. Cardio only keeps your heart rate
elevated for minutes after you finish. If you lift weights BEFORE you run,
you'll be able to get your heart rate up with far less effort than you would if
you ran first. It's a no-brainer!
Don't Forget to Warm-Up

good bye fat |
The
only time you should do cardio BEFORE weight training is your warm-up. It's recommended
that you spend at least 5 to 10
minutes running or cycling just to get your heart beating and your blood
pumping. It will help to warm up your muscles, and will make it easier for you
to stretch and dive right into your workout.
