3 Barbell Complexes For Rapid Fat Loss

3 Barbell Complexes For Rapid Fat Loss

There are fewer cliches more popular than the "bang for your buck" one that is tossed around in the fitness world. The reason being is everyone wants a potent dose of training that delivers results, fast. Also, it's a great selling point for any training program. Who doesn't want to get shredded in 8 minutes?

While the efficacy of these claims are for another article, I think it's worth pointing out there is a such thing that can allow you to build and maintain a respecter amount of muscle in your attempt for fat loss.

Meet the barbell complex. A complex is two or more movements done with a barbell with the same load done consecutively for reps without setting the weight back to the floor.

Before we get into the three complexes, let's go over some ground rules and some FAQ's.

Olympic Lifts

All complexes use some variation of an Olympic lift. You must learn how to do the Olympic lifts first, before you attempt to do a complex. Seek out a professional Olympic lifting coach.

An article or a YouTube video is helpful, but in person coaching is imperative. Don't underestimate them. Granted that you have solid Olympic lifting foundation, it's time to have some fun with some complexes.

Frequently Asked Questions

1. Won't my nervous system get wrecked if I stack the required amount of reps needed in a complex?

After a heavy lifting session-heavy, as in using a very close maximum weight, it's normal to feel exhausted. You feel wiped out, similar to a dead battery with no juice left. A wave of slothfulness and low motivation may hit. You'll experience this after attempting PRs or a huge competition.

If you train to constantly set records day in and day out you will burn out, constantly. Training at your absolute max or very close to it on a daily basis is a surefire path down to frying your nervous system. Zatsiorsky called the burn-out of constant maxing "staleness."

But before you proudly place yourself in this category, you probably aren't training nearly hard enough to worry about such a thing. Over-training can cause a landslide of problems like low testosterone, low motivation, lack of concentration, decreased appetite, etc...

I'm not discounting it as the fact that it exists, but I think the fact that you are now aware of over-training is the exact cause you under-training. It's what you do know that is holding you back from training hard.

Lastly, when you're attempting to use complexes to burn fat, it's important that you use an appropriate load to prevent from burn out and to maximize intensity. We'll get into that shortly.

2. Can a complex be used as a workout all on it's on?

Yes. The barbell is one of the most efficient ways to move a load quickly across large distances. This sets up an incredible environment for improved conditioning and fat loss. In fact, if fat loss is paramount, then training with complexes may be superior to doing traditional straight sets.

Studies have shown that doing shorter high-intensity resistance training (like a using a complex) may increase resting energy expenditure improving fat oxidation.

The Barbell Complex Warm Up

Instead of holding a toe touch, perform a full body dynamic warm. Warming up in this manner will prepare all of your systems to ensure that you perform most efficiently for your lifts.

A good warm-up should affect the heart, blood vessels, nervous system, muscles and tendons, along with the joints and ligaments.

Additionally, a good warm-up will sharpen your reaction time, enhance concentration, improve coordination and regulate your mental and emotional state. 
  • 5-10 minutes of aerobic activity (jog, jump rope, bike, row)
  • 5-10 minutes of dynamic stretching and mobility work (bodyweight movement patterns, jump squats, push-ups, planks, mobility work, foam rolling, voo doo flossing)

Why is this better than old-school stretching?

  • The aerobic activity will prepare your cardiovascular system for exercise.
  • The dynamic stretching will not only prepare your joints and ligament for similar movements you'll be doing in your workout, but it will also raise and maintain body temperature as you enter your workout. (static stretching can drop your temperature).

The Barbell Complexes

#1 - The Bear Complex

  • Power clean 7 reps
  • Front squat 7 reps
  • Push press 7 reps
  • Back squat 7 reps
  • Push press 7 reps

Complete 3-5 rounds. Rest 2-4 minutes between sets.

#2 - The Bret Contreras Barbell Complex

This one is from Bret Contreras. Typically the bar isn't supposed to leave your hands or touch the floor once you initiated the complex, he breaks that rule in this one. It's still an awesome complex.
  • Power curls 6 reps
  • Push press 6 reps
  • Back squat 6 reps
  • Good mornings 6 reps
  • Glute bridge 6 presses
  • Floor press 6 presses

Complete 3-5 rounds. Rest 2-4 minutes between sets.

#3 - The Dan John Barbell Complex

This one comes from Dan John. This complex holds true to what he defines as a complex. The barbell only leaves your hands or touches the floor after all the lifts are completed.
  • Row 5 reps
  • Clean 5 reps
  • Front squat 5 reps
  • Press 5 reps
  • Back squat 5 reps
  • Good mornings 5 reps

Complete 3-5 rounds. Rest 2-4 minutes between sets.

What To Expect

Even though the reps are kept low on each movement, don't sleep on the level of intensity these complexes will bring. Get ready for some serious oxygen debt.

If you hate intervals, sprints, pushing a sled, tabatas or high rep anything, then utilizing a complex for fat burning might be a perfect match for you.

You can expect a short, potent workout that torches the fat while minimizing muscle loss. And, you can escape the soul-sucking, bored out of your skull activity of walking on a treadmill for cardio.

Barbell Complex Re-cap

1. Load properly

You'll be using the same load for movements in each complex, so don't load up your 3RM and attempt to do 20+ reps with it. A general approach is to load the barbell at a weight that allows to barely complete the required reps on your weakest exercise in the complex. This movement is typically anything that goes overhead (press, push press, push jerk).

2. Flow

Each movement in a complex should flow right into the next. This explains why most complexes start from the floor with some type of deadlift variation and end in a pressing movement or the bar passes overhead into a back squat or good morning.

3. Warm up properly

You'll have a better experience with your complex if you warm up properly. I'm not saying it'll be easier, but you'll get a lot more out of your workout.

4. Use them as a workout, as a finisher, or to feed your OCD

Five rounds of a complex can be a workout all on its own. But you can also use them as a finisher to a traditional straight set strength workout. You can also use them as an 'extra' day at the gym, when your OCD kicks in and you can't take a rest day. If you aren't using the complex as your main workout, use a lighter load.

5. Keep it in check

First, get coached on how to do the Olympic lifts. Second, when you're able to perform complexes, don't go crazy. They aren't meant to be performed 5-6 times a week. 2-3 complexes per week done with the right load and intensity is plenty.
