That level is just a minimum maintenance level. If you really want to increase your level of fitness or lose weight, you should exercise at least six times a week. Many people mistakenly believe that exercising for an hour one day is equal to exercising a half-hour for two days. Or, working our really hard for two hours over two days gives the same benefit as working out in four thirty minute sessions. Wrong on both counts.
Consistency is the most important factor in exercise fitness .
Consistency wins over quantity every time and anaerobic exercise is generally superior to aerobic exercise, especially for weight management. Anaerobic exercise is any type of exercise activity that allows the individual to maintain a controlled level of oxygen consumption. There is an easy way to know the difference. In anaerobic exercise, you will be able to carry on a normal conversation while you are exercising. If you can't do that, then you have slipped into an aerobic phase.
