You surely saw one of them on the treadmil, walking for half an hour with his cell phone at his hear talking in the same time for half an hour. That is no workout!

People start eliminating fat from their diets thinking that will make them immediately lose weight, without even thinking about what specialists say: some fats are good for you! Others start eating more times per day, in smaller quantities because this is how you should eat to help out your body. Again, they do not understand that you need to eat properly not less.

A cardio workout is not effective unless combined with a diet. You can not loose weight if you consume 300 calories and drink a protein shake after your workout that brings in 500 calories. Loosing fat is easy but you can not do it by exercise alone! How long will it take till people understand this?
