What is Full Intensity Training and how does it work?
Full Intensity Training is a unique type of exercise utilizing multiple joint movements and full body exercisies to deliver an unmatched level of stimulus on the metabolism. F.I.T. provides real results in less time by:
  • Using full body exercises so clients burn maximum calories in minimum time.
  • Generating the correct intensity to release hormones for fat burning.
  • Creating an increased metabolism that lasts hours and even days after exercise.
  • Adding fat burning “machinery” to the body so clients burn more calories at rest.
  • Using exercises that develop enhanced body function and increased fitness.
  • Constantly changing the workout so the body never knows what’s coming.


Full Intensity Training provides results simply, efficiently, and consistently. There is no cumbersome equipment, no distractions, and no thinking. A Group Personal Trainer will guide clients through the workout, one exercise at a time, taking the guess work out of exercising. All the client has to do is show up ready to work, the Trainer will do the rest.

Full Intensity Training (F.I.T.) workouts develop:
  • strength
  • speed
  • agility
  • balance
  • coordination
  • stamina
  • muscular endurance
  • cardiovascular/respiratory conditioning

F.I.T. workouts focus primarily on guiding clients through functional, multi-joint movements utilizing weight implements, bodyweight, gravity and inertia to apply appropriate resistance for all skill levels.
The beauty of Full Intensity Training is all fitness levels can participate in and benefit from the workout- each person's definition of Full Intensity will be different. Additionally, as you continue to consistently complete the F.I.T. workouts, your Full Intensity Training Ultimate Level will increase in proportion to your progress. Your progress and success are cumulative, every workout building on top of your previous one, at your own pace.
Workout intensity is individualized by using exertion rates. The F.I.T. Exertion Scale (FES) uses a color code system to express and guide intensity.
F.I.T. Exertion Scale:
  • Green: You are at rest and your muscles are not being exerted
  • Blue: You are at moderate exertion, you can still talk, and feel moderate muscle discomfort
  • Yellow: You are at high intensity, you no longer want to talk, and/or your muscles are nearing failure or are burning
  • Red: You are at extreme intensity, you have to stop or slow exercise, and/or your muscles have reached full mechanical and/or metabolic fatigue (a "F.I.T. Point").
Clients may defer to Minimal Intensity Training (Blue) activities once they have reached a F.I.T. Point (Red). These are known as "MIT's" and include walking, jogging, jumping jacks, or other low intensity movement.
The workout proceeds at the pace of the individual participants. They can get water and rest whenever they need to.
Full Intensity Training is based on the well-researched exericise data available on a metabolic phenomenon known as "lactic acid threshold".

What is Lactic Acid Threshold?

The lactic acid threshold is the exercise intensity at which lactic acid starts to accumulate in the blood stream. The reason for the acidification of the blood at high exercise intensities is two-fold: the high rates of ATP hydrolysis in the muscle release hydrogen ions, as they are co-transported out of the muscle into the blood via the MCT— monocarboxylate transporter, and also bicarbonate stores in the blood begin to be used up. This happens when lactic acid is produced faster than it can be removed (metabolized) in the muscle. When exercising at or below the lactic acid threshold, any lactic acid produced by the muscles is removed by the body without it building up.

Full Intensity Training takes advantage of the body being able to temporarily exceed the lactic acid threshold, and then recover (reduce blood-lactic-acid) while operating below the threshold and while still doing physical activity. Full Intensity Training, Interval Training *, and Fartlek** are similar, the main difference being the structure of the exercise. Full Intensity Training can take the form of many different types of exercise. F.I.T. workouts will identify and develop highly functional human movements and postures, and encourage replication of some of the core movements found in high level sport.
In addition to causing a burning sensation, lactic acid also causes an increase in growth hormone. Growth hormone helps to break down fat. Full Intensity Training forces your body to produce high amounts of lactic acid, increasing loss of fat. The amount of growth hormone released in Full Intensity Training can be up to nine times the amount produced under normal circumstances.
According to Olympic coach and strength expert Charles Poliquin, "The lactic acid pathway is better for fat loss than the commonly accepted aerobic pathway... High blood lactic acid levels decrease blood pH levels, which in turn sends a message to the brain to accelerate its production of growth hormone. Higher growth hormone levels increase fat loss."
Since Full Intensity Training has both hormonal and caloric effects, it is able to deliver superior results in less time than most other exercise programs.

*Interval training is a type of discontinuous physical training that involves a series of low- to high-intensity exercise workouts interspersed with rest or relief periods. The high-intensity periods are typically at or close to anaerobic exercise, while the recovery periods involve activity of lower intensity. Interval training can be described as short periods of work followed by rest. The main aim is to improve speed and cardiovascular fitness.

**Fartlek, which means "speed play" in Swedish, is a training method that blends continuous training with interval training.  The variable intensity and continuous nature of the exercise places stress on both the aerobic and anaerobic systems. It differs from traditional interval training in that it is unstructured; intensity and/or speed varies, as the athlete wishes.  Most Fartlek sessions last a minimum of 45 minutes and can vary from aerobic walking to anaerobic sprinting. Fartlek training is generally associated with running, but can include almost any kind of exercise.
