Reason #1 : Cardio is Enough
Dr. Kenneth Copper the father of aerobic is finally admitted aerobics itself is not the one and only solution to fat loss. However, the latest survey stated over 80% women still not put the resistance training into their weight loss program. Why exercising with resistance is necessary ? The amount of calories that you burn during exercise is pretty minimal. The vast majority of the calories burned because of exercise are burned in the hours after you have finished exercising. And the length and amount of this ‘after-burn’ are determined by both the intensity of the exercise and the amount of muscle used during the exercise period..not by the amount of time spent exercising!!! So remember…you can exercise hard, or you can exercise long…but you can’t exercise hard for long.
Reason #2 : Resting Too Long Between Sets During Resistance Training
I have seen many people in the gym, who spend their resting time by checking messages in their phone or talking to the person who is next to them.
When you exercise a muscle, you are ‘breaking the muscle down’…tiring it out. However, the human body is a fascinating machine. The muscle that you just exercised to failure will regain about 50% of its initial strength in the first of 10 seconds rest. After one minute the muscle will regain its strength by 90%. So, if our purpose is to ‘break the muscle down’ with exercise, why on earth would we want to let it recover (almost) fully between sets? That means that we are starting each set almost from the beginning again. How inefficient is that?
Reason #3 : Poor Technique
You have the best fitness program that no one can beat, incredible motivation and amazing nutrition plan. But if you are not performing the exercises correctly, your results are still going to be far from optimum. Any exercise that is not performed correctly will only result injury. And if you are not performing the exercise correctly, you may be exercising completely different muscles than you think you are.
Reason #5 : Doing Outdated Exercise
We are living in the year 2012 now where many exercises have been improved and modified in order to minimize injury. Open up yourself to different types of exercise so you always have options and avoiding plateau. It's time to freshen up your routine and give yourself challenges in exercise.
Reason #6 : Crunches Help Lose Belly Fat
There is no proof doing 100 reps of crunches will shed the fat around your belly. Studies have shown that the belly fat area is most responsive to cardio and diet ( avoiding refined carbs, sugar and trans fat ). Speed up the process by cardio and resistance training. My favorite is planks. I still do crunches but limited only to 20 reps and do back up afterward.
