Why is cardio so important?
Cardio is important because it strengthens your heart and therefore it does not have to work as hard to pump blood through your body.
How do you get the most out of each cardio session?
I suggest doing cardio in the morning before your first meal. Your body is most likely to use fat as the energy source because your glycogen stores are depleted. If you are concerned about muscle loss, take 15-25 grams of whey protein before your morning cardio session.
Any tips to make it a little easier?
Make a cardio playlist on your iPod to get you through the workout. Pick out your favorite songs that you love listening to so you forget about the time.
Aerobic exercise is also important for weight control and it is great for blasting fat. To avoid getting strung out on running, mix up your cardio routine as much as possible. There are plenty of fun cardio exercises such as kickboxing (which I love), bicycling, using the elliptical, swimming, and even step aerobics. This way you will keep you body guessing and your heart pumping!
