Metabolic Training VS. Steady State Aerobics

Metabolic Training = Conditioning exercises performed with the intention of increasing the capacity and efficiency of the energy pathways to store and deliver for activity.
In Lay Men terms = conditioning exercises that causes you to react to high and low intensities that will help you store energy for use and continue durring throughout your day
Example : Interval training with weights or body weight
Circuit training on machines
Compound exercises with different types of equipment
Interval training while running, swimming, biking, etc.

Steady State Aerobics = A level of metabolism when the oxygen consumption satisfies the energy expenditure and the heart rate required for oxygen transport stabilizes
In Lay Men terms = Steady state aerobics done at a constant pace usually based off of a percentage of VO2 or Target Heart Rate Zone.
Example:Running on a treadmill or outside, Elliptical, Riding a bike, Swimming, Rowing, etc.

The question is which is better? Well, in my personal opinion a combination of the two works great for preventing boredom and plateaus. Metabolic Training is more efficient and the one I prefer, but I love a good ol' mindless run outside on a beautiful day too. If you are wanting better results in a shorter amount of time then Metabolic is the way to go. If you are maintaining then getting in your exercise should do the trick. Keep in mind that weight training is necesary for all to help prevent boneloss. A minimum of 2 times per week is my recommendation. Remember check with your doctor before you start any new activities if you have previously been living a sedentary lifestyle.
