Strengthening Your Core
If there is one indication that someone is fit, it is a tight and lean stomach. Men and women alike hope that eating right and putting in hard work at the gym will earn them a perfect six-patch. Unfortunately, the opposite is also true. The rising popularity of fast food has led to an increase of obesity rates and waistlines around the globe. If someone is out of shape, you will notice the extra weight around their midsection. In both cases, a person’s core muscles seem to tell a lot about their fitness and eating habits. Many people associate the core with just the stomach area, but science actually defines it as our body without arms and legs. Although many people want a solid core to look good, the development of these muscles affects many areas of our lives. In athletics and general life for that matter, we all rely on our core muscles heavily to get things done. Studies have shown that athletes who build a powerful core foundation aren’t injured as much. Meanwhile, the benefits of your average Joe may be even greater. Ordinary people use their core muscles for nearly every task they do. This includes picking things up, sitting in a chair, or tying your shoes. Our core muscles provide stability, so we can keep our balance and easily move in any direction. If we neglect them, life can become much more difficult. As a result, we should always consider our core muscles when designing our workouts. However, if you have been sedentary for years, performing thousands of repetitions will probably get you injured. Instead, start off slowly and gradually build up your numbers. An excellent exercise for both beginners and advanced exercisers is the plank. You simply get in an extended pushup position as if you have just finished a rep. Maintain this position, but place the weight on your forearms instead of your hands. Then, hold the position as long as you can. You should feel your core muscles working hard to help your hands and support the weight of your body. In the beginning, you may only be able to hold it for a few seconds, but keep at it. The Guinness World Record for abdominal planking is three hours and seven minutes.
