Hello,
There have been alot of great responses and you have gotten a lot of goood advice. I wanted to throw in my 2 cents.
Cardio: You need to do cardiovasular exercises to decrease the amount of excess fat you have in that area. For weight loss, you should be performing at least 30 minutes of cardio exercises at least 5 times per week. Cardio is anything that gets your heart rate up for an extended period of time, such as biking, walking, running, swimming and aerobic classes. You can use machines like the elyptical, treadmill or bike or you can perform the exercises without machines and using your own body weight.
Strength training: The next thing you need to incorporate is strength training. That means lifting weights. Strength training will help you to tone up your muscles and give them form and shape. Why is that important? The more shape and form you have to your muscles, the stronger you are and the more energy your muscles will use to stay that way. The energy that they use is the excess body fat that you are probably carrying around in your mid section. Excess fat is used by the body as energy.
I hear from women all the time that they don't want to strength train because they are afraid of "bulking up." Don't worry about bulking up, you would have to lift so much weight and do so much suppplements and probably some steriods in order to "bulk up" and look manly that you wouldn't even consider it anyway.
I have been strength training since 1999 and certified as a personal trainer who works almost exclusively with women since 2005. I use my knowledge to help my clients get the body that they have always wanted. Most of them come to me wanting to tone up and that is what they get, by using the same methods that I am suggesting to you.
Also, I love classes, so yes, get involved in Pilates, Yoga aerobics and so forth, but don't forget about the weights. Not only will strength training with weights help you to increase the muscle tone in your body and help you burn excess body fat, it will also help you to strengthen your bones so that you can stay strong and agil during your later years. That way, you can enjoy your children now and still look great as they get older and into adulthood and people will start to wonder who is the child and who is the parent.
If I can be of further assistance, please don't hesitate to contact me and Good luck!
