Increase growth hormone and testosterone

Human growth hormone triggers growth and cell reproduction. HGH is naturally found in the body but the levels of it are higher in children and young adults, decreasing as you get older. Testosterone (found in body) is the key male sex hormone that regulates fertility, muscle mass, fat distribution and red blood cell production. Testosterone although higher in males is present in females also, decreasing with age usually after 25. HGH and testosterone are essential for building muscle and being healthy

Functional Fitness

Moving weight is ok. Moving your body will save lives. 

Fitness : The condition of being physically fit and healthy / The quality of being suitable to fulfil a particular role or task. (Google dictionary). Functional fitness focuses on core stability and prepares you for carrying out everyday tasks and even life threatening situations. Ask yourself why are you training. Is it for "looks" or is it for what I wrote in the first line of this post. If its the first one, you're wasting your time. Having the bulging muscles of an onstage bodybuilder is not fitness, nor does this give you endurance or flexibility. Having visible abs but you can't get up without using your hands means your abs are weak and hence unfit. 

Don't believe what you hear

Many people think they know everything or something about health and fitness. But you can never know everything. Everyday you can learn and become better but first you must be open minded and believe the facts; not what you hear. When even the Government, food labels and so called fitness experts are telling us false facts, you can see why people are struggling. When supermarkets are selling chocolate that is "sugar free"and the Government is "alarmed" at the statistics of obese people in the UK, this takes misleading to another level.
