5 Reasons Why You Should Perform Quick, Intense Workouts – PLUS 3 Intense Workouts To Get You Started By: Prath Shah

Hey Fam! This week I’m posting one of Prath Shah’s articles on my site. This same article with a video can be found over at ShahTraining.com. Prath has some really good information over at his site, plenty of body weight routines and information. I have posted 3 of his articles here and I visit his regularly, so I suggest you check him out.
Lower intensity exercisesuch as aerobics and distance running burn body fat during the actual activity. This is because the body uses blood and stored sugar as an energy source in the first 15-20 minutes of activity. After this period, the body switches to fat as a fuel source. This is the reason why most trainees tend to do hours of cardio per week. 

This form of training is highly inefficient simply because the calories we burn during activity do not help us burn fat. Our long term weapon against fat relies on our resting metabolic rate (RMR, or a measure of calories we burn while at rest) and certain hormones in our body.

Low intensity training does nothing to raise your RMR, nor does it stimulate any fat-burning hormones such as HGH (human growth hormone). In fact, excessive cardio can release Cortisol , also known as the stress hormone. This is a bad hormone, as it increases one’s appetite and also converts calories into abdominal fat. The following are five reasons why you should be performing quick, intense workouts for better health and fat loss:

Reason #1:

Less Time Commitment for Better Results

 

  • Our bodies are extremely efficient at adapting to training stimuli. In order to continue getting results from our workouts, we need to either make them more intense or make them last longer (increase time). Most individuals will perform low-intensity, longer duration training.
  • In this scenario, lets assume it takes a person 30 minutes to burn off 300 calories. As his body become more efficient, he will now need to spend 35,40,45 minutes to burn off 300 calories. Over time, it becomes impractical to do more work for the same amount of results.
  • Instead of increasing time and lowering intensity, decrease time and increase intensity. Doing so will force your body to work harder, thus burn more calories in the long run (explained below). The most important thing is that you’ll save time.

Reason #2:

The Power of EPOC

 

  • The higher the intensity of the exercise, the more likely you will use carbohydrates as an energy source rather than fat. However, even though you are using carbohydrates as the primary fuel source with high intensity training, the total amount of calories burnt off will be much greater through high intensity exercise than with low intensity exercise.
  • This is because after an intense workout , our bodies experience oxygen and metabolic debt. It needs to return to homeostasis. This process of regaining a balanced state is known as excess post-exercise oxygen consumption (EPOC). A number of processes take place during EPOC including the restoration of various energy sources, re-establishment of normal ventilation and heart rate, restoration of normal core body temperature, and re-oxygenation and restoration of blood and circulating hormones.
  • These processes require energy in the form of calories to take place. Studies have shown that this process can take up to 48 hours to complete, meaning that your metabolism will be on fire 48 hours after engaging in an intense exercise session, depending on the level of intensity of the workout.

Reason #3:

Eat Carbs, Lose Fat

  • As mentioned earlier, with high intensity training, you are burning carbohydrates (glycogen stores) as an energy source. When you use your glycogen stores during high intensity exercise, they are less likely to be stored as body fat. And after exercise, during EPOC, you body needs to get calories from somewhere to repair the damage done by your workout.
  • If you do not replenish your glycogen stores (eat carbohydrates) after an intense workout, then your body will go to its fat stores for energy. Research has shown that interval training increases the activity of enzymes involved in fat burning.
  • This means that after high intensity training, there is more fat in the blood (free fatty acids), meaning that more fat is being used for energy production. The best news for me is that I can still consume carbs and burn off fat.

Reason #4:

Boost your HGH

 

  • High intensity training can also boost your levels of human growth hormone (HGH), which promotes the reduction of body fat. HGH is produced naturally in the pituitary gland. This hormone is vital for stimulating our body’s metabolic cycles, and has been linked to fat loss, strength gain, and increases in lean muscle mass.
  • A 2002 study in Britain’s Journal of Sports Scienceshowed that 30 second sprint intervals increased levels of human growth hormone (HGH) by 530 percent. In addition, a 2003 study published in the Journal of Clinical Endocrinology and Metabolism stated that proper exercise can “mimic the effects of HGH treatment.”

Reason #5:

Double your Endurance

 

  • High intensity training also does a better job of boosting your endurance levels than steady state cardio. After just two weeks of interval training, six out of 8 college students double their endurance according to a 2005 study published in the Journal of Applied Physiology.
  • The other 8 volunteers in a control group, who did not do any interval training, did not show any improvement in endurance. The amazing aspect of this study is that all volunteers were already reasonably fit. The results were attained after just 15 minutes of intense cycling spread out over 2 weeks.
  • The ability of the heart and lungs to supply oxygen to working muscles improved 13 percent in a 2007 study published in the Journal of Applied Physiology. The study involved 8 women in their early 20’s who cycled for 10 sets of four minutes of intense cycling, followed by 2 minutes of rest.

I would not be doing proper justice if I did not provide some sample workouts to help you get started with high intensity training:

Workout #1:

Perform max rounds in 20 minutes of:

 

  • 10 Burpees
  • 5 Chinups

Best: Performed 7 Rounds
Workout #2:

21 Reps of each for time:

 

  • Sumo Deadlift High Pull, 95lbs
  • Push Press, 95lbs
  • Hindu Pushups
  • Kettlebell Windmills
  • Kettlebell Thruster
  • Squat Jumps
 

 Workout #3:

3 rounds of:

  • Incline Pushups – 2×30 seconds, 30 seconds rest
  • Chinups – 2×30 seconds, 30 seconds rest
  • Rowers – 2×30 seconds, 30 seconds rest
  • Hindu Squats – 2×30 seconds, 30 seconds rest
  • Ankle Grabbers – 2×30 seconds, 30 seconds rest

Use this knowledge and these workouts to improve your health and burn some fat!
