an excellent exercise, you can do it in front of your TV: sit on a
stool, and put your toes under something (piece of heavy furniture, for example). In your hands hold a little dumbbell. Please, make sure that it is not very heavy, start with one kilo, for example, or you will damage your back and spine!
Slowly move the upper part of your body back, until it's parallel with the ground. Stop for a second and move it back to the sitting position. Repeat ten times.
Every week add to the number of repetitions.
You will see the results in a week, guaranteed! You will see or feel under the fat - if you have any - six pack and muscles. Dumbbells do wonders. Much better than these crunches - I came up to three hundreds and there was no results AT ALL. With the dumbbells you will see it in a week.
That's for toning.
For weight loss, go wheat free. No pasta, pizza, bread and so on. And no food after 7 p.m.
I know a woman who lost 60 pounds a month on it. She did nothing else!
