The word fitness is hard to define without the boredom of quoting the dictionary we may as well say it can mean a lot. A marathon runner is fit, a 60 meter sprinter is fit, a body builder looks fit, a thin person looks fit. What is strange is that all of these people are very different in physical make-up. Fitness is indeed a strange term to nail down. The best way to analyse fitness is to break it into two categories Anaerobic fitness and Aerobic fitness. Aerobic fitness is the muscles ability to perform a repetitive exercise with maximal speed and power. Aerobic power is the heart and lungs ability to provide a constant supply of oxygen to the muscles over an extended period of time. So what is the best kind.
I see many people jogging for miles and miles in pursuit of fitness many killing themselves getting up an 6 a.m. to go running just to achieve this goal. Going back to the unfortunate truth that appearances are everything the reality is that long distance running has the effect of increasing leg mass and decreasing upper body mass creating a sort of pear shape. This is in stark contrast to the perfect egg timer shaped fit body. Whereas the smarter trainer might spend three hours a week in the gym and achieve that figure with ease. Anaerobic 1 Aerobic 0.
Going back some years in Athletics the main source of fit science aerobic training was the norm however as time goes on the focus is shifting on Anaerobic development through more intelligent form of weight lifting. So it can be said that while a certain amount of Aerobic ability is necessary the main source of physical advantage is borne through anaerobic fitness through strength conditioning. www.inno-v8.com - Hammerstep the hamstring squat expert check it out.
