Burn Fat in 8 Seconds

After a long winter it’s no doubt that we all put on a few extra pounds. Summer is on the horizon and you know you’ll have to shed your winter wear, exposing those soft spots around your belly and love handles.

Unfortunately, the average student usually has too much on their plate from commuting to school to late night cramming sessions. This leaves no time for long intensive workouts at the gym.

What if we can get more out of our workouts with less time and less effort?

Too good to be true?

Well a team of scientists out of Australia might have solved this problem for all us “busy” people. Dr. Boutcher and his team placed 45 overweight women through their SPRINT-training which is a short, high-intensity training based on cycle sprints over 12 weeks. They discovered a significant drop in their abdominal fat and an increase in muscle mass.

Nothing out of the ordinary, high-intensity training has been known to be a great fat burning workout, but this is where it gets very interesting.

It was found  1 hour  SPRINT-training a week burns the same amount of body fat in men as jogging for 7 hours a week.

So what is SPRINT training?

Using a fitness bike, you sprint for 8 seconds, followed by 12 seconds of exercising lightly for a total of 20 minutes. You would perform this 20 minute exercise three times a week for a total of 1 hour of exercise a week, which should fit in anybody’s schedule.

Why does it work?

“We think the reason that it works is because it produces a unique metabolic response,” said Professor Boutcher.

During the intermittent 8 second sprinting large amounts of catecholamine is released. A specific hormone that is involved in oxidizing fat storage which results in greater weight loss.

Furthermore, with this short burst of high intensity output with a longer period if normal output hinders the build up of lactic acid in your muscles. This is that painful burn you feel when your muscles are actually doing work, in simple terms this type of training helps prolong your workouts because it takes longer for your muscle to tire out.

This kind of exercise is great for people who don’t have time to spend hours in the gym, and even better you only require a stationary bike which is not that expensive to purchase for yourself.

Lastly, Dr. Boutcher notes that “Overall, any type of exercise is good. You just have to work out your objectives, whether it is to increase muscle, lose fat, or enhance other aspects of your life such as improving the quality of your sleep.”

G-Flux: Formula for a Superior Body Composition

The popularity of fitness training seems to have increased exponentially over the past couple of years or so. Fortunately, this means that people generally are more educated about how to train and eat properly. However, although people are finally realizing that the “less is best” diet is the most effective, many individuals who are mindful of caloric intake and expenditure do not know that there is an association between the level of this energy balance and body composition. Enter John Berardi‘s principle of G-flux.

John Berardi argues that a higher energy balance, that is, a higher amount of energy into the body accompanied by higher energy expenditure by the body, is superior for body composition. So how does G-flux work? Take, for example, an individual who does little to no physical activity from week to week. This person’s daily requirement of calories to maintain their current body composition will be low, due to low energy expenditure. If the same individual were to engage in five to seven hours of weekly physical activity, their energy expenditure will be much higher. Provided that the energy taken into the body (food eaten) balances the caloric expenditure, energy balance level or G-flux, will be higher. G-flux says that the net effect of this higher energy balance is a body that not only possesses a superior composition, but performs better, also.

Some might ask how the body can produce a better composition while still taking in maintenance levels of calories. Many experienced athletes, fitness buffs and studies will tell you that in order to cut fat, a caloric deficit must be achieved – the amount of calories taken into the body (through food) is less than the calories burned through exercise and other activities. This is a tried and true method for leaning out the body, but in a state of caloric deficit the body builds little to no muscle, and other effects such as fatigue may occur. In a state of high G-flux, however, the body is in an environment where fat loss is promoted through intense and frequent activity while still being able to build muscle at maintenance calories.

How can you increase your G-flux? Simply increase your weekly exercise. Choose physical activities that are relevant to your fitness goals and do them for a minimum of five to seven hours a week, while increasing your food intake accordingly to achieve that higher energy balance.

Easier Alternatives to Cardio?

About 2 weeks have passed since the start of a new year and gyms everywhere have been consistently filled with hopefuls who are determined to improve their overall body composition in time for the upcoming beach season. These trainees often make treadmills and stationary bikes their home away from home, dedicating countless hours in a day in order to burn off that extra bit of unwanted fat.

Despite the amount of hard work and effort put it by plenty of gym-goers, gym attendance unfortunately declines as the year progresses. Many people lose hope due to their obtained results not living up to their initial expectations. While fat loss is no walk in the park, it definitely is not the nightmare many people seem to think it is.

If you were to ask anyone off the street, they would most likely mention that hours upon hours of running or biking is the key to fat loss. However, a more efficient strategy to improve one’s body composition could be defined in two parts. The first component involves setting caloric restrictions on an individual’s diet to achieve body fat reduction. In order to do this, you need calculate your body’s total daily caloric requirements and aim to eat below this amount. Mifflin et al. proposed the following equation to calculate this number:

For men:
BMR = [9.99 x weight (kg)] + [6.25 x height (cm)] – [4.92 x age (years)] + 5
For women:
BMR = [9.99 x weight (kg)] + [6.25 x height (cm)] – [4.92 x age (years)] -161

In the above formulas, BMR stands for basal metabolic rate. This value represents the minimum amount of calories your body needs to consume in order to maintain vital processes like breathing and gastrointestinal activity. Mifflin et al. multiplied the results of the BMR equation by an activity factor ,  which was based on the lifestyle of the individual,  to determine the total amount of calories required for the entire day.

Studies have shown that by simply reducing daily food intake  below an individual’s total daily caloric requirement over a period of 24 weeks resulted in a 27% decrease in total fat mass in men and a 22% decrease in total fat mass in women. This loss in fat was independent of the amount of cardiovascular exercise done by participants of the study.

While it is true that you can lose fat on a calorie restrictive diet alone, it doesn’t mean one can’t lose muscle mass as well. The second part of the strategy to improve body composition is the incorporation of resistance training which can help retain an individual’s useful lean body mass. In the study above, participants that underwent daily caloric restrictions and resistance training 3 days a week still exhibited overall body fat reduction and their ability to lift weights showed no signs of decrease for the entire duration of the 8 week study.

Although the benefits of doing cardiovascular activity on a regular basis are important, its excessive use should not be seen as an individual’s main tool for reducing fat around the body. Instead, by monitoring what you eat and adding some weight training into the mix, you can make the journey towards improving health and fitness a bit more bearable.
