Your energy redefined:
Do you know which energy system(s) you use when you workout and how they contribute to getting you to your fitness goals? Unless you are a trainer you likely don't know the answer to this question, even though it is one of the most important factors in reaching your fitness goals, whatever they are.
Your body operates on three different energy systems: phosphagen system, glycolysis, and aerobic system and these three systems are generally divided into two types of exercise: anaerobic and aerobic exercise. I could go into how each of these three systems work on a biological level but that would go against simplifying how you can utilize these systems to maximize every minute of your training sessions.
Although the terms aerobic and cardio are widely used interchangeably I'd like to change that for the sake of simplicity and workout design. In this article and for our boot camps we define aerobic exercise as any exercise utilizing major muscle groups in repetition for more than 2 minutes in duration at a steady heart rate of around 65% of your maximal heart rate, which focuses on improving your aerobic energy system. Cardio will be defined as any exercise that uses a load of 0% to 25% of your body weight at a duration of 20 seconds to 2 minutes, at a variable heart rate that tops out at 90% to 95% of your maximal capacity, which improves both your aerobic and glycolysis energy systems. Anaerobic exercise will be any exercise done at a load above 25% of your body weight for a duration of less than 20 seconds that pushes your heart rate to 95%+ of maximal, which improves your phosphagen energy system and increases lean muscle mass. There is a lot of dispute, even in the science, of where these lines should be drawn but you have to draw them at some point in order to create workouts that help you progress and actually get you to your goals.
If we look at how exercise is defined in the two energy system manner, you will see that jogging, swimming, and biking are generally regarded as aerobic exercise and standard exercises like squats, chest press, and curls are considered anaerobic exercises. But what about basketball, high intensity interval training, push ups, sprints, and calisthenics in general? Well, they also fall into anaerobic exercise. Basketball? That doesn't make much sense to me to be lumped in with a pyramid set of chest press: the goal of each and their effect on our physiology are too different to be considered in the same category and so I treat them as categorically different when I construct my workout plans. This is why we use aerobic, cardio, and anaerobic as three separate terms with three different meanings.
Creating your training schedule:
If you have time and you want to build the perfect training schedule you will need to train all three energy systems for a split that suits your fitness goals. Everybody should create their own split that emphasizes their personal goals such as increasing lean muscle mass, increasing heart health, or maybe reducing bodyfat, but for the sake of the general population I would recommend this split: 1 hour a week of anaerobic training done one day a week, full body; 2.5 hours of cardio training, done 5 days a week split into 30 minute sessions; and 3 hours of aerobic training done 4 days a week in 45 minute sessions. If you don't have the time for this kind of split, cardio training 2 to 3 hours a week split into 30 minute bouts a day would be the best use of your time to reach any fitness goal you may set.
Anaerobic Training
The duration of each training session is important because we don't want to overtax any one of your energy systems, rather we want to maximize their potential and stop before we overshot the sweet spot. I only recommend 1 day a week of pure anaerobic exercise because if performed to failure, in sets lasting less than 20 seconds, you will need to recover sufficiently before returning to another anaerobic session, which can take three days or more if you are not including other training in your schedule. I recommend a full body workout isolating muscle groups going in order of larger groups to smaller, for example; perform all of your chest exercises before moving onto tricep exercises or training your lats and upper back before performing bicep exercises. I also recommend splitting upper body muscle groups with legs, for example: do back and biceps, legs, chest and triceps, then finish with abs. This is just an example, if your goals are to increase lean mass in your chest then I would start there as an example of customizing the split to your personal goals.
In your anaerobic training session you will want to use a weight and rep count that will put you to failure or near failure (significant spotting required) in just under 20 seconds. This will help to increase your lean muscle mass in targeted muscles as well as increase testosterone levels to help the growth of other muscles in your body. Side note: by not giving adequate attention to your legs you are missing out on a huge testosterone boost for upper body gains.
Aerobic Training
Your aerobic workout should be the least complicated of all. Find an activity that you can do for no less than 20 minutes and optimally for up to 45 minutes that activates major muscle groups repetitively for the full duration of the workout. I am a disabled veteran with multiple surgeries on my ankles, which affects my knees, so running is out therefore I go with road biking personally. Getting a bike fitted to you or going to a store that analyzes your running form can go a long way to giving you a pain free aerobic training experience. Aerobic exercise should be performed without any pain in your muscles or joints besides the occasional burn on an incline or cramps towards the end.
Cardio Training
Your cardio training is going to be the most complicated and rewarding part of your training regimen. for this reason we will be leaving to part 2 of this article as it is the foundation of our training program and deserves our full attention.
This is a continuing series, please scroll past the exercise theory to get to the exercises if you have read this before.
There are five basic types of exercise that we utilize in our boot camps, these exercise categories include:
Exercise order is very important, so if I give you a list of exercises, please follow the order or their is a possibility of injury or you just won't get the full benefit of the workout. Generally speaking here is the order we follow in most boot camps:
Circuit training is another way to break down large quantities of repetitions while keeping the intensity high. In a circuit, several exercises are scheduled in rapid succession with only a few reps of each. In this circuit you are not allowed to rest between exercises. Use a 30/30 Interval and follow the exercise order precisely. Take a 60 second rest period after completing all the exercises in the circuit this may be walking or standing.
Circuit #1 (Performed on bench seat)
Tabata Intervals to be repeated 3 times before moving to the next exercise:
Circuit #2 Same as number one but performed on right foot.
Circuit #3
Tabata Interval to be repeated 1 time through before repeating circuit:
Cool down with walking for 30 to 60 seconds and then some static stretching. If you'd like to make this a longer workout you can turn it into a Parkour workout. All you need to do is jog from one bench area to another inbetween the circuit workouts. If this is too intense you can switch the intervals to 30/10, which will give you a little rest period inbetween each exercise.
I hope you enjoy the workout and we'll see you when we get back!

We may be gone for the week but that doesn't mean you can't get out there and workout on your own. You'll be fine if you don't, you'll just have to suffer through a couple boot camps before your body adjusts again but if you don't want to lose that momentum, then try this workout throughout the week and you'll be ready for when we get back.

In the first of a two-part series, I’ll explain the various elements that go into creating a boot camp fitness program and then walk you through the process of creating your own. At the end of this article, you’ll find two sample battle plans you can use as examples.
There are five basic types of exercise, and you may include some or all of them in your boot camp program, depending on what you’re trying to achieve. Exercise categories include:
Cardiovascular exercise does the most to burn fat during exercise. Cardiovascular exercise, like running, quickly depletes the energy stores that muscles prefer to use and forces them to burn fat for energy. Studies show that cardiovascular exercise burns the most fat when done at a moderate pace that increases heart rate but allows the trainee to hold a conversation. Fat burning due to cardiovascular exercise stops soon after heart rate and breathing rates return to normal.
Resistance training burns little fat during the exercise compared to cardiovascular exercise, but it has a longer lasting fat burning effect on the body. An increase in metabolism from resistance training can last for hours, and resistance training increases muscle size and density, which causes the muscle to burn more calories every time it’s used. Muscle growth results in a more or less permanent increase in calorie consumption, which is essential to long term fat loss.
Agility, speed and plyometric training can burn fat like cardiovascular exercise when it raises the heart rate high enough for an extended period. They can also spur muscle growth and its resulting calorie consumption, similar to resistance training but not as effectively. Stretching has little impact on fat loss, though when done with enough intensity, stretching can increase metabolism and overall calorie consumption.
For a boot camp program that catches fat in the crossfire, emphasize resistance training and cardiovascular work.
A major source of problems affecting the skeletal and muscular systems of the body is muscle imbalances. A muscle imbalance occurs when muscles on one side of a joint are significantly stronger or more developed than those on the opposite side. Avoid a program that promotes muscle imbalance by including resistance exercises for all of the following muscle groups:
One of the things that separates boot camp fitness programs from typical gym programs is the emphasis on compound exercises. Where many fitness club programs with resistance training emphasize isolation exercises, which involve exercising the muscles for only one joint at a time, the efficiency required of boot camp programs demands the use of compound exercises that utilize multiple joints and muscle groups at a time. For example, the barbell curl is an isolation exercise that works the biceps, while the pull up is a compound exercise that works the biceps, lats in the upper back and the serratus. Nearly all of the exercises included in the next section are compound exercises.
Cadence refers to the tempo or speed at which trainees perform repetitions. In the military, recruits do their push ups and other calisthenics to the same beat, usually dictated by the drill instructor. You may wish to do the same with your boot camp platoon, or you may want to let trainees do them at their own speed and tempo. If you are dictating the cadence, you can control the intensity of the exercise by speeding up or slowing down the cadence.
Another trait that sets boot camp programs apart from the typical fitness club program is the variety of exercises, intensity and schedule. Boot camp programs keep trainees on their toes with program changes from day to day and week to week. This variety prevents the body from getting accustomed to the workout, which cues an internal response to adapt to new conditions and better prepares the trainee to handle whatever life throws at him or her. Here are six ways to add variety to your program:
Most boot camp programs are geared for people who, previous to enlisting in your program, have not exercised much or at all. In those cases, you need to start the program at a level your recruits can handle. That doesn’t mean they won’t moan, groan, wail and cry trying to fulfill the program’s requirements. It just means you don’t want to over train or injure them so they can’t continue the program. Here are a few strategies for making sure new recruits can stick with it:
Because this is boot camp and not nursery school, you’ll want to progress fairly quickly to a more difficult program. Progression is essential to growth and development. The body adapts and stagnates in ability fairly quickly, so you have to continually challenge it to keep muscles growing and metabolism advancing. Here are six ways to add progression to your program:
Intensity refers to how hard the trainee works to do the prescribed exercises. In the early weeks of your program, you’ll want to start with a relatively low intensity and progressively increase the average intensity each week. You’ll also want to vary the intensity within each daily session because most of your recruits will not be able to maintain anything but a low intensity workout for the duration of a workout session. By including some low intensity portions of the workout, you give trainees an opportunity to recover and prepare for more high intensity work.
For five day programs, you’ll want to vary the intensity of workouts within the week. They need the challenge of some high intensity days, but if they’re all high intensity, trainees will over train and are more likely to incur injuries.
You can increase the intensity of a workout in three ways:
Likewise, you can decrease the intensity of a workout in three ways:
When deciding what order to schedule the exercises in a session, consider the following:
Ladders are one way of breaking down high repetition sets to make them more manageable by beginning trainees. They are used extensively in military physical training programs. With ladders, trainees start by doing one rep, take a 15 second rest, do two reps and continue on in this fashion until half the set is done or the trainee cannot complete the mini set. Then they work back down the ladder doing one rep less than the last mini set until they reach zero. So a set of 25 reps would be broken down into the following mini-sets: 1-2-3-4-5-4-3-2-1 with 15-second rests in between.
Circuit training is another way to break down large quantities of repetitions while keeping the intensity high. In a circuit, several exercises are scheduled in rapid succession with only a few reps of each. Trainees are allowed little to no rest between exercises, but they get a rest period after completing all the exercises in the circuit. Then trainees repeat the circuit a designated number of times.
Here's an example of a circuit (to be repeated 3 times):
In Part 2 of this series, I will provide you with the boot camp planning and schedule forms and guide you through the step-by-step process of using these forms, as well as example boot camp workout programs for both the three-day and five-day fitness boot camp programs.
