Could CV Exercise Be Making You Fat?

Now that I got your attention, let me clarify; Cardiovascular (CV) exercise doesn’t directly make you fat. However, it can work against you if you are trying to lose fat.

A few key facts about cardio exercise and resistance training'

Cardio exercise
• Cardio is your best source for expending calories per unit of time.
• Cardio also can be catabolic (destructive process of breaking muscle tissue down for fuel) relative to maintaining lean body mass.

Skeletal muscle
• Muscle is your metabolism.  The more you have, the faster your metabolism.
• Muscle is where body fat is metabolised (burned) for fuel in presence of oxygen (aerobic exercise).
• Muscle at rest is metabolically active.  It burns calories throughout the day when not exercising or at rest.
• Muscle occupies less space than body fat. This is essential if you are trying to lose inches and get thin!

Individuals who only do cardio exercise, because of its catabolic nature, may over-time sacrifice muscle in the process. When this occurs, individuals are basically making their metabolism less efficient to burn calories. This is why it isn’t unusual for individuals who fall into this category to find themselves doing more and more cardio exercise to just maintain their current weight.

Also, as you increase your level of cardiovascular fitness, you body becomes more efficient at using calories.  This is a natural  part of the fitness improving process.  Basically, it means that you have to do more and more in order to burn off the same amount of calories.

All quite vicious and circular!

This is not to say not to perform cardio exercise; as it plays a key role in losing and/or maintaining weight.

Rather this statement is to bring attention to effective body transformation and long-term weight management. This can be accomplished by activating skeletal muscle with progressive resistance exercise in conjunction with your cardio workouts and can be the difference between getting the results you always wanted and spending more time doing cardio exercise while not seeing results.

Another worry with this lack of concern for muscle is when an individual has to reduce their cardio activity due to various reasons (illness, injury, work, vacation, etc.) they gain weight back much easier and quicker because of the less lean body mass and lowered metabolism.

So keep on moving those weights!

Ladies, don't worry, lifting weights won't turn you into Mrs Arnold Swarzenegger!  HONEST!!!
