It is a never ending mantra. If you want to lose weight, you must eat right and exercise.
And there are many ways of exercising. You can run, walk, swim. Those are considered cardio workouts.
But what about strength training? These are resistance exercises, where a muscle is isolated and worked for strength. You can go to the gym and use their weight training machines or buy your own machine if you have the space and the money.
I saw an ad in a magazine of an exercise machine that claims that you can exercise in 4 minutes a day and have a great body! No kidding.Do you know how much it costs? … $14,615 ! Who can afford that? Certainly not me.
In fact, I used to go to the gym but now since it’s gotten so expensive I am working out at home. I use two 5 pound dumbells, some floor excercises and best of all my band set.
It is a fitness set that fits in a small bag made by Bodylastics. Quite frankly, for under $50 I got myself a variable resistance system that I can use with in my own home. And the best part is that they offer online video instruction once you buy the product. 
The way it works is that you use elastic bands that have handles and perform certain movements to work specific muscles. Some of the exercises require you to connect the elastic to a door and others are created by simply standing on the elastics.
