Firstly, the hypothalamus (situated in the brain), assists in the release of gonadotrophin releasing hormone to the anterior pituitary gland, which, in turn, releases luteinizing hormone, which travels to the Leydig cells of the testes and stimulates the enzymatic conversion of cholesterol to Testosterone. In order to increase testosterone levels through exercise is to concentrate on working the larger muscle groups. But it is recommended to avoid training the same body-part two days in a row. The increased intensity level can be achieved in the morning when testosterone levels are at their highest. At this period you can make greater gains. You should perform low repetitions while lifting a correspondingly heavy weight if you want to boost testosterone. 85% of ones one-repetition-maximum for 1-2 reps is best. In fact the best way to increase the testosterone levels is to perform a short, intense, anaerobic session. The short aerobic training (45-minute sessions) are ideal for this purpose because testosterone in this period is exceeded. Growth Hormone
Growth hormone is a very important bodybuilding hormone which is released from the brains pituitary gland. It assists in stimulating protein synthesis, strengthening bones, ligaments, tendons and cartilage. It plays a crucial part in fat mobilization, and the corresponding decrease in carbohydrate usage, during exercise. As a result, body fat is used and blood glucose levels are balanced which gives the opportunity to train longer (without exceeding the testosterone maximizing 45-minute period of course). The benefits of the increases in growth hormone are numerous, among which are increased energy, ability to concentrate, and interest and ability in sex. IT also provides longer-term benefits such as increased aerobic capacity and strength, thickening of hair, tightening of wrinkles and loose skin, decrease in visceral fat, and strengthening of osteoporotic bones. The production of growth hormone reduces significantly as we age and this is one of the negative effects of aging. However you shouldn’t go to extremes, the level of growth hormone can increase through exercise.
The most effective exercise to boost growth hormone in the body is vigorous, sustainable anaerobic training. You should use the same strategy as when training for testosterone release concentrating on the large muscle groups, the quads in particular. You workout should last no longer than 30 minutes when specifically aiming to increase growth hormone. The same concerns the aerobic training. It should be undertaken at a very high intensity; bordering on anaerobic. Interval training is the best choice. Estrogen
When this hormone is in its most biologically active form (17 beta estradiol) it can bring a lot of benefits among which are fat mobilisation for fuel, mood elevation, increased basal metabolic rate, and libido ( mostly in women). With age the estrogen levels in the female body vary with the purpose to regulate the reproductive system. The level of estrogen is reduced significantly by the time the women reaches menopause.
