Do you know that a Mom deserves a special gift this year for Mother’s Day? Sure, flowers can always brighten Mother’s day and a dinner out is always appreciated. However, doesn’t she deserve something more personal or something that lasts longer than an evening?

I’m talking about the gift of fitness. Improved fitness is a gift that is invaluable to everyone. When you give a woman the gift of fitness, you are helping her open a door to better health. I can’t think of a more thoughtful gift that shows the recipient(接受者) how much you care about their well-being. By giving the gift of fitness you are providing them with unlimited health benefits. And, its a gift that you can truly feel proud to give.

Of course, we all know that exercising can help people stay slim and fit. But, do you also know about all the other great benefits of exercising? Daily physical activity reduces stress and can help you sleep better. Fitness has been linked to reducing the risk of some diseases and to warding off depression. Researchers also believe that strength training can help prevent osteoporosis(骨质疏松). Not to mention that exercising also improves self-esteem, increases energy and helps you be able to do continuous work for longer.

All Moms would find these fitness benefits extremely invaluable. If they are like most of us, they have probably even mentioned how they would like to drop a few pounds or just get in better shape. In fact, experts say that about 62% of Americans are currently on a diet. By giving the gift of fitness you are helping provide your mom with extra motivation. She may be more motivated to actually get fit because she doesn’t want to feel guilty about ignoring such a thoughtful gift .
