It is common to hear fitness professionals and medical doctors prescribe low to
moderate intensity aerobic training (cardio) to people who are trying to prevent
heart disease or lose weight. Most often, the recommendations constitute
something along the lines of “perform 30-60 minutes of steady pace cardio 3-5
times per week maintaining your heart rate at a moderate level”. Before you just
give in to this popular belief and become the “hamster on the wheel” doing endless
hours of boring cardio, I’d like you to consider some recent scientific research that
indicates that steady pace endurance cardio work may not be all it’s cracked up to
be.

First, realize that our bodies are designed to perform physical activity in bursts of
exertion followed by recovery, or stop-and-go movement instead of steady state
movement. Recent research is suggesting that physical variability is one of the
most important aspects to consider in your training. This tendency can be seen
throughout nature as animals almost always demonstrate stop-and-go motion
instead of steady state motion. In fact, humans are the only creatures in nature
that attempt to do “endurance” type physical activities. Most competitive sports
(with the exception of endurance running or cycling) are also based on stop-and-go
movement or short bursts of exertion followed by recovery. To examine an
example of the different effects of endurance or steady state training versus stop-
and-go training, consider the physiques of marathoners versus sprinters. Most
sprinters carry a physique that is very lean, muscular, and powerful looking, while
the typical dedicated marathoner is more often emaciated and sickly looking. Now
which would you rather resemble?
Another factor to keep in mind regarding the benefits of physical variability is the
internal effect of various forms of exercise on our body. Scientists have known that
excessive steady state endurance exercise (different for everyone, but sometimes
defined as greater than 60 minutes per session most days of the week) increases
free radical production in the body, can degenerate joints, reduces immune

function, causes muscle wasting, and can cause a pro-inflammatory response in
the body that can potentially lead to chronic diseases. On the other hand, highly
variable cyclic training has been linked to increased anti-oxidant production in the
body and an anti-inflammatory response, a more efficient nitric oxide response
(which can encourage a healthy cardiovascular system), and an increased
metabolic rate response (which can assist with weight loss). Furthermore, steady
state endurance training only trains the heart at one specific heart rate range and
doesn’t train it to respond to various every day stressors. On the other hand,
highly variable cyclic training teaches the heart to respond to and recover from a
variety of demands making it less likely to fail when you need it. Think about it this
way -- Exercise that trains your heart to rapidly increase and rapidly decrease will
make your heart more capable of handling everyday stress. Stress can cause your
blood pressure and heart rate to increase rapidly. Steady state jogging and other
endurance training does not train your heart to be able to handle rapid changes in
heart rate or blood pressure. Steady state exercise only trains the heart at one
specific heart rate, so you don’t get the benefit of training your entire heart rate
range.
The important aspect of variable cyclic training that makes it superior over steady
state cardio is the recovery period in between bursts of exertion. That recovery
period is crucially important for the body to elicit a healthy response to an exercise
stimulus. Another benefit of variable cyclic training is that it is much more
interesting and has lower drop-out rates than long boring steady state cardio
programs.
To summarize, some of the potential benefits of variable cyclic training compared
to steady state endurance training are as follows: improved cardiovascular health,
increased anti-oxidant protection, improved immune function, reduced risk for joint
wear and tear, reduced muscle wasting, increased residual metabolic rate
following exercise, and an increased capacity for the heart to handle life’s every
day stressors. There are many ways you can reap the benefits of stop-and-go or
variable intensity physical training. One of the absolute most effective forms of

variable intensity training to really reduce body fat and bring out serious muscular
definition is performing wind sprints or hill sprints. Also, most competitive sports
such as football, basketball, racquetball, tennis, hockey, etc. are naturally
comprised of highly variable stop-and-go motion. In addition, weight training
naturally incorporates short bursts of exertion followed by recovery periods. High
intensity interval training (varying between high and low intensity intervals on any
piece of cardio equipment) is yet another training method that utilizes exertion and
recovery periods. For example, an interval training session on the treadmill could
look something like this:
• Warm-up for 3-4 minutes at a fast walk or light jog
• Interval 1 - run at 8.0 mi/hr for 1 minute
• Interval 2 - walk at 4.0 mi/hr for 1.5 minutes
• Interval 3 - run at 10.0 mi/hr for 1 minute
• Interval 4 - walk at 4.0 mi/hr for 1.5 minutes
Repeat those 4 intervals 4 times for a very intense 20-minute workout.
The take-away message from this section is to try to train your body at highly
variable intensity rates for the majority of your workouts to get the most beneficial
response in terms of heart health, fat loss, and muscle maintenance. This e book will quickly help you flatten abs and lose belly fat.
