Peak Fitness Boosts Your Human Growth Hormone by 771% in Just 20 Minutes

Story at-a-glance -

  • Most people are making major mistakes in their exercise programs as aerobic or cardio workouts miss out on important hormonal and health regulation benefits achieved by performing high-intensity, burst-type exercises such as Peak Fitness.
  • Peak Fitness exercises are far more effective as they promote human growth hormone (HGH), a synergistic, foundational biochemical underpinning that addresses the serious muscle loss and atrophy that typically occurs with aging.
  • Your production of vital human growth hormone increases by up to 771 percent during a Peak Fitness workout because you are stimulating your fast muscle fibers, which are rarely used during most exercise programs.
  • Because these exercises are so intense, you only need to do them three times a week, and the entire workout takes just 20 minutes. Doing them more often can actually be harmful, as your body will not have enough time for recovery.

Phil Campbell is a true veteran in the field of fitness with over 35 years experience in training professional athletes.

Over the years Phil has worked with 18,000 athletes, teaching them how to run faster with the proper speed technique.

Phil helped me understand how to practically change my primarily cardio aerobic exercise program to one that actually increases growth hormone and provides more health benefits.

You may not be aware that I first became interested in health and fitness in 1968 when I read Dr. Ken Cooper's book, Aerobics.

In the '60s, exercise was not embraced by the health and medical profession, and Dr. Cooper was the catalyst for increasing the overall awareness about exercise.

I followed his aerobic program for over 40 years as a runner and then, about five years ago, Dr. Al Sears opened my mind to the possibility that high intensity exercise training was superior to the cardiovascular aerobic-type training I had been using for over four decades.

But Phil Campbell helped me understand the connection to human growth hormones (HGH) and how to practically integrate the program. I have been doing Phil's program, referred to as "Sprint 8" in the video but which we refer to as Peak Fitness on our site, now for two years it's really made a remarkable difference in my fitness level.

Why Long, Slow Cardio Doesn't Deliver Desired Results

For those who are not yet familiar with Peak Fitness, it works because it engages your fast and super-fast twitch muscle fibers, which promotes human growth hormone (HGH), a synergistic, foundational biochemical underpinning that helps make your strength training and everything else work like a charm, and effectively burns off calories.

Phil explains:

"Most exercise programs today are built based upon a very incomplete picture of the physiology of your body. For example, long slow cardio, "calories in, calories out," would be a perfect way to look at the body if it were all slow-twitch fiber … [but] there are three muscle fiber types: slow, fast and super-fast … both those types of fast-twitch fibers are essentially 50 percent of your muscle fibers that don't get recruited until you add a velocity of movement."

If you don't actively engage and strengthen all three muscle fiber types and energy systems, then you're not going to work both processes of your heart muscle. Many mistakenly believe that cardio works out your heart muscle, but what you're really working is your slow twitch muscle fibers. You're not effectively engaging the anaerobic process of your heart. Fortunately Peak Fitness type exercises however, do address these fibers and metabolic systems.

Traditional strength training and cardio primarily exercise your slow twitch muscle fibers. Your body kicks in these slow twitch muscles first, in an effort to not recruit your fast twitch muscles, or work your heart anaerobically.

This is why you may not see results even though you spend an hour on the treadmill a few times a week – you're basically denying the natural physiology of your body by not working the other half of your muscle fibers; your fast-twitch muscles.

Phil states:

" … the American Heart Association and the American College of Sports Medicine, they have taken long-slow cardio and have taken it out of the exercise guidelines and the reason is pretty clear. It just doesn't work. It doesn't work both processes of your heart muscle, aerobic process and anaerobic process. It doesn't work for your fast-twitch fiber.

To really work your cardiovascular system the way you should, I'm now saying you do moderate-intensity cardio (which is still pretty intense) five days a week for 30 minutes ─ or vigorous intensity cardio for 20 minutes, three times a week. This is what Sprint 8 has been for years and years now."

You Should NOT do Peak Fitness Every Day

I want to point out that even though Peak Fitness is, in my impression, an essential, crucial element of any exercise training program -- it is NOT something you should do every day, as your body requires more time to heal in between sessions.

Phil says:

"We have to urge caution because research is pretty clear now: if you do long and slow exercise, your muscle -- that's slow-twitch fiber -- can heal pretty quickly in one day. But when you work fast-twitch fiber, whether it's an NFL athlete, or me or anyone, it takes about 48 hours for that fast-twitch fiber to truly heal back and totally recover. Sprint 8 is one of these programs that you really don't want to do every day … we recommend three times a week."

The benefit of doing this program three times a week comes not only from the way it works your fast and super-fast muscle fibers, but also the way it increases your growth hormone with each session.

Each Peak Fitness Workout May Increase Your Growth Hormones by 771 Percent

Human growth hormone is often referred to as "the fitness hormone." The higher your levels of growth hormone, the healthier and stronger you will be. Once you hit the age of 30, you enter what's called "somatopause," at which point your levels of human HGH begin to drop off quite dramatically. This decline of HGH is part of what drives your aging process, so maintaining your HGH levels gets increasingly important with age.

The longer you can keep your body producing higher levels of HGH, the longer you will likely experience more robust health and strength. Some athletes choose to inject it for this very reason, though it is a banned substance in nearly every professional sport. I do not recommend injecting HGH however, due to the potential side effects, the cost and, more importantly, it is likely to cause more long-term harm than good. Fortunately, your body produces HGH naturally when you exercise your super-fast muscle fibers during vigorous, high-intensity exercise like Peak Fitness.

Phil explains:

"You know, walking is a great thing, but it only works the aerobic process of your heart muscle. It doesn't work the anaerobic process. It only recruits your slow-twitch fibers. So those two other muscle fiber types are meant to be used to exercise is necessary to release growth hormones.

… If we look at the body and say, how do you want us to exercise? When you do this – when you do Sprint 8 –
