Everything You Need to Know About Metabolic Conditioning

High intensity training is all the rage these days beause they offer two very important things that other workouts don't: Shorter workouts and a lot more calories burned than most traditional cardio or strength training workouts.

Metabolic conditioning is just one of those killer high intensity workouts. Also known as MetCon, this type of training involves a very high work rate using exercises designed to burn more calories during your workout and maximize calories burned after your workout, or your afterburn.

In other words, these are very hard high intensity circuit-type workouts that often involve challenging total body compound exercises and very short recovery intervals. Less recovery time means spending more time in your anaerobic zone, a zone we can only stay at for about 2 minutes before we have to stop and rest.

It's ​in this zone that we condition the body, burn more calories and train the body to endure high intensity exercise.

MetCon is most recognizable in programs such as P90X, Insanity, and CrossFit - Programs known for pushing the human body to its limits with fast-paced cardio and strength exercises designed to build both strength and endurance.

Plenty of people do these programs to get lean and lose weight, and most of them would tell you these are very advanced, very challenging workouts that are guaranteed to make you work harder than you ever have if you strictly adhere to the exercises.

Types of MetCon Training

There are different types of training out there available, depending on your goals or, in some cases, your job.

  • Tactical metabolic conditioning for firefighters, military or law enforcement personnel, etc.
  • Metabolic conditioning for performance - For example, a professional athlete might use MetCon to train for certain sports or events
  • For health and fitness - This is where most of us will fall when trying MetCon, and our purpose is, most often, to lose weight.

The Basics of a MetCon Workout

The term metabolic conditioning doesn't really describe a specific workout, but more a type of workout designed to challenge the two major energy systems that contribute to exercise.

Strength training often relies most on one type of energy system, ATP, which fulfills our immediate need for fuel.

Moderate cardio uses glycolysis to fuel our bodies over longer, slower exercise sessions.

Metabolic conditioning is able to target both of these energy systems in the same workout by using high intensity whole body movements along with a very short work-to-rest ratio.

That means you go from one very hard exercise to the other with little or no rest in between. You do this for certain intervals, anywhere from 20 seconds to more than 2 minutes, to tax your body, your mind, and your energy systems. Some examples of exercises you might do in a typical MetCon workout include burpees, lunge jumps, pushups or bear crawls, just to name a few.

Should You Try MetCon?

Whether you try MetCon is based on your goals, your fitness level and what you want out of your workouts. Programs like P90x, Insanity and CrossFit can help people lose weight - The sheer volume and intensity of the training will make sure of that.

However, that kind of high volume and intensity is best left to people with a long history of exercise who can handle taking their bodies and training to the next level.

Workouts that are too intense for beginners can lead to injury, burnout, severe muscle soreness and the strong desire to quit altogether.

However, that doesn't mean you can't try a version of MetCon in your own workouts. In fact, there are simple ways to bring this concept into your own training without the gut-wrenching intensity.

Getting Started With MetCon

If you're not ready for the intensity of things like CrossFit or P90X, there are some things you can do in your own workouts to slowly build the endurance and power you need for more vigorous workouts:

  • Practice circuit training. Circuit training, whether you're doing strength circuits, cardio circuits or a combination, embodies the very concept of MetCon, taking you from one exercise to another with either very short rests or no rests between exercises. Practice by doing your exercises one after another with 30 or more seconds between exercises. As your fitness improves and you get used to this kind of training, start reducing the rests each time, going down to 10-15 seconds or, eventually, removing them altogether. This simple act will increase the metabolic demand on your body and that's what MetCon is all about. 
  • Change different elements in your workouts. Changing the metabolic demand on your body can be as simple as lifting heavier weights, working a little harder during cardio sessions, trying interval training, doing combination exercises or even putting short bursts of cardio into your regular strength training program.
