Many people have a strong desire to lose weight. To get rid of that belly fat and get into really good shape. They imagine taking their shirts off and getting some amazing attention from the desired sex. Many people spend hundreds or even thousands of dollars in pursuit of this activity.
However, if you are only thinking about your outward appearance, then you are missing a large piece of the health puzzle. Remember, one main reason, and some say the only reason, is to exercise is to that you can improve your health. How you look with your shirt off is merely a secondary effect. The real reason is to lower your resting heart rate, lower your cholesterol and blood pressure, and extend your life.
That's why smart people like you choose exercises that satisfy both of these elements. Killing two birds with one stone. And one of the best exercises you can is to strengthen your core. What is your core? It's those big muscles around your midsection. Your abs, your obliques, and your back muscles. In short, every time you move your upper body, you are involving your core.
Why are these important? Because for one, if you neglect these muscles, it's much easier to get injured. Strained backs are a huge cause of lost work and lost income. You can easily avoid these injuries by doing some simple core exercises every day.
You can kill a bunch of birds with just two exercises, and also mix up some horrible metaphors, if you catch my drift. The first exercise is your basic sit-up. Lay on your back, bend your knees a little bit, and then sit up. Don't worry about twisting, or crunching, or anything like that. Just sit up, rest, and slowly go back down. Don't fret about how many you can do or how fast you can do.
Next is the neck bridge. This is great for your back. Lay on your back, then bend your knees, so your feet are flat on the floor. Then slowly put your weight on the bottoms of your feet, and slowly walk them back towards your butt. As you do this, roll back onto the crown of your head. When you get to where you look kind of like an upside down letter "U," with your weight evenly distributed on the crown of your head and the soles of your feet, just hold it there for a couple minutes. The longer you can hold it, the better.
Simply by doing these two exercises, you'll be doing a lot of good for your core. The rest of any workouts you do will be safer, and you'll have much better posture.
