Do you know the rationale behind idle worship? Those people who find it difficult to concentrate on an abstract entity as god prefer to view it in the form of a physical object. It may range from a stone to a beautifully crafted piece of cloth.
At the end of the day, it is important to remember that the ideal is merely a manifestation and that one should focus on the abstract for ultimate salvation. Well, the same approach is pretty much applicable during fitness regimen as well. We all like to measure the time that we have exercised.
We often feel that we have done a good job when we have exercised for one or two hours at a stretch. On the other hand, excising for just ten minutes is often considered a bad move.
Well, using time as a mode of measuring the quantum of work done may help people keep track of their fitness regimen. However, you should stop equating duration with fitness. Just because you have exercised for two hours does not mean you are going to become very fit.
If you spend 15 minutes taking rest after exercising for 5 minutes, you probably would have excised for not more than 30 to 40 minutes in entire stretch of two hours. Hence, do not focus on quantity alone.
Quality matters as well. If you exercise for 10 minutes a time and three times a day in a religious manner, you will probably be fitter than another individual who exercises for two hours a day but only once or twice in a week. Do not complain about fitness despite exercising a lot when you equate lots of exercise with lots of time.
