PRODUCE HGH with Exercise

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. 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 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.
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. Here's a summary of what a typical Peak Fitness routine might look like:
Warm up for three minutes
Exercise as hard and fast as you can for 30 seconds. You should feel like you couldn't possibly go on another few seconds
Recover for 90 seconds
Repeat the high intensity exercise and recovery 7 more times

As you can see, the entire workout is only 20 minutes. Twenty minutes! That really is a beautiful thing. And within those 20 minutes, 75 percent of that time is warming up, recovering or cooling down. You're really only working out intensely for four minutes!

Keep in mind that you can use virtually any type of equipment you want for this  an elliptical machine, a treadmill, swimming, even sprinting outdoors although you will need to do this very carefully to avoid injury  as long as you're pushing yourself as hard as you can for 30 seconds. But do be sure to stretch properly and start slowly to avoid injury. Start with two or three repetitions and work your way up, don't expect to do all eight repetitions the first time you try this, especially if you are out of shape.

Abstract

Human growth hormone (hGH) is secreted in a pulsatile fashion, generally following a circadian rhythm. A number of physiological stimuli can initiate hGH secretion, the most powerful, non-pharmacological of which are sleep and exercise. hGH has many varied roles throughout life, from growth itself, including the turnover of muscle, bone and collagen, to the regulation of selective aspects of metabolic function including increased fat metabolism and the maintenance of a healthier body composition in later life. The exercise-induced growth hormone response (EIGR) is well recognised and although the exact mechanisms remain elusive, a number of candidates have been implicated. These include neural input, direct stimulation by catecholamines, lactate and or nitric oxide, and changes in acid-base balance. Of these, the best candidates appear to be afferent stimulation, nitric oxide and lactate. Resistance training results in a significant EIGR. Evidence suggests that load and frequency are determining factors in the regulation of hGH secretion. Despite the significant EIGR induced by resistance training, much of the stimulus for protein synthesis has been attributed to insulin-like growth factor-1 with modest contributions from the hGH-GH receptor interaction on the cell membrane. The EIGR to endurance exercise is associated with the intensity, duration, frequency and mode of endurance exercise. A number of studies have suggested an intensity 'threshold' exists for EIGR. An exercise intensity above lactate threshold and for a minimum of 10 minutes appears to elicit the greatest stimulus to the secretion of hGH. Exercise training above the lactate threshold may amplify the pulsatile release of hGH at rest, increasing 24-hour hGH secretion. The impact of chronic exercise training on the EIGR remains equivocal. Recent evidence suggests that endurance training results in decreased resting hGH and a blunted EIGR, which may be linked to an increased tissue sensitivity to hGH. While the potential ergogenic effects of exogenous GH administration are attractive to some athletes, the abuse of GH has been associated with a number of pathologies. Identification of a training programme that will optimise the EIGR may present a viable alternative. Ageing is often associated with a progressive decrease in the volume and, especially, the intensity of exercise. A growing body of evidence suggests that higher intensity exercise is effective in eliciting beneficial health, well-being and training outcomes. In a great many cases, the impact of some of the deleterious effects of ageing could be reduced if exercise focused on promoting the EIGR. This review examines the current knowledge and proposed mechanisms for the EIGR, the physiological consequences of endurance, strength and power training on the EIGR and its potential effects in elderly populations, including the aged athlete.
