Nxt Level’s new Mens Comfy Chair

We have just purchased a new comfy chair for the male members of our gym. Any suggestions where we should put this seat? We are working on getting  an anatomically correct one for the ladies too.

We’ve all heard it before, the theory that doing cardio on an empty stomach after an overnight fast sends fat burning into overdrive. If only it were true…By: Brad Shoenfeld

The Myth Of Cardio Before Breakfast-Debunked!

In 1999, Bill Phillips published his bestselling fitness book, Body-for-Life, which promised a body transformation in 12 weeks.

In his cardio chapter, Phillips put forth the theory that performing aerobic exercise first thing in the morning on an empty stomach maximizes fat loss.

The rest, as they say, is history. Ever since, every Tom, Dick, and Harriett has been shuffling off to the treadmill each morning before raising so much as a spoonful of oatmeal to his or her lips.

His rationale was as follows: A prolonged absence of food brings about a reduction in circulating blood sugar, causing glycogen (stored carbohydrate) levels to fall. That leaves your body no choice but to rely more on fat, rather than glucose, to fuel workouts.

Moreover, the low insulin levels associated with fasting are conducive to fat breakdown, increasing the availability of fatty acids to be used as energy during the exercise session.

The strategy became popular with bodybuilders and other physique athletes striving to get as lean as possible. After all, who wouldn’t want to burn more fat while expending the same amount of effort?

Here’s why:

Measuring Your Morning Cardio And Metabolism

First and foremost, it’s shortsighted to simply look at the number of fat calories burned during an exercise session. Your metabolism doesn’t operate in a vacuum.

Rather, the body continually adjusts its use of fat and carbohydrate for fuel depending on a variety of factors.

As a general rule, if you burn more carbohydrate while exercising, you’ll ultimately burn more fat in the post-workout period and vice versa (¹).

In the end, it doesn’t make a bit of difference. You need to evaluate fat burning over the course of days–not hour to hour basis–to gain a meaningful perspective on its impact on body comp.

Let’s say you’re a skeptic, though, and figure it’s better to burn more fat now rather than later. A bird in the hand is better than two in the bush, right? Well, not in this case.

True, the research does show that fasted cardio can increase fat utilization during exercise compared to performing cardio in the fed state. Except this only occurs at very low levels of training intensity.

During moderate-to-high intensity levels, the body continues to break down significantly more fat when fasted compared to after you’ve eaten.

So far, so good. Unfortunately, the rate of breakdown exceeds your body’s ability to use the extra fatty acids for fuel. In other words, you have a lot of extra fatty acids floating around in the blood that can’t be used by working muscles.

Ultimately, these fatty acids are repackaged into triglycerides post-workout, and then shuttled back into fat cells. So you’ve gone to excessive lengths…only to wind up at the same place.

Fasted Cardio Doesn’t Mean Fast Results

Okay, so perhaps you’re thinking that you’ll just perform fasted low-intensity cardio to burn those few extra fat calories. Nice try, hot shot. You see, training status also has an effect on the fasted cardio strategy.

Namely, if you exercise on a regular basis–and if you’re reading this article, that likely includes you–the benefits of fasted cardio on fat utilization are negligible even at low levels of intensity.

Horowitz and colleagues (²) found that when trained subjects exercised at 50 percent of their max heart rate, an intensity that equates to a slow walk, there was no difference in the amount of fat burned–regardless of whether the subjects had eaten.

These results held true for the first 90 minutes of exercise; only after this period did fasted cardio begin producing a favorable shift in the amount of fat burned.

So unless you’re willing and able to slave away on the treadmill for a couple of hours or more, fasted cardio provides no additional fat-burning benefits, irrespective of training intensity.

Fasted cardio makes even less sense when you take into account the impact of excess post-exercise oxygen consumption. EPOC, commonly referred to as the “afterburn,” represents the number of calories expended after training. Guess what? Eating before exercise promotes substantial increases in EPOC (³).

And guess where the vast majority of calories expended in the post-exercise period come from? You got it, fat!

Take home message: More EPOC equals more fat burned. This favors eating prior to performing cardio

There’s also the intensity factor to consider. Research indicates that high-intensity interval training is more effective than steady-state cardio for fat loss (Bill Phillips actually recommended H.I.I.T as the preferred type of cardio in his book).

Ever try to engage in H.I.I.T session on an empty stomach? Bet you hit the wall pretty quick. In order to perform at a high level, your body needs a ready source of glycogen; deplete those stores and say goodbye to elevated training intensity.

The net result is that fewer calories are burned both during and after exercise, thereby diminishing total fat loss.

On top of everything, fasted cardio can have a catabolic effect on muscle. Studies show that training in a glycogen-depleted state substantially increases the amount of tissue proteins burned for energy during exercise (⁴).

Protein losses can exceed 10 percent of the total calories burned over the course of a one-hour cardio session–more than double that of training in the fed state (⁵).

Any way you slice it, sacrificing hard-earned muscle in a futile attempt to burn a few extra calories from fat doesn’t make a lick lot of sense–especially if you’re a bodybuilder!

To Cardio Or Not To Cardio Before Breakfast

Summing up, the strategy to perform cardio on an empty stomach is misguided, particularly for physique athletes.

At best, the effects on body composition won’t be any better than if you trained in a fed state; at worst, you’ll lose muscle and reduce total fat loss. So if you should eat…what should you eat prior to cardio?

The answer depends on several factors, including the duration and intensity of training, the timing of previous meals before the cardio session, and individual genetics.

A good rule of thumb is to consume approximately 1/4 gram of carbohydrate and 1/8 gram of protein per pound of your ideal bodyweight (which may differ from your actual weight).

For example, if your ideal bodyweight is 200 pounds, then your pre-workout meal should consist of approximately 50 grams of carbs and 25 grams of protein. A shake made of natural fruit juice and whey protein is a good option, particularly if cardio is done early in the morning before breakfast.
