As we age, our body naturally changes its shape causing us to be pitched forward. You can, however, delay this process with proper attention to posture and body mechanics, weight control, and improving core strength. There are many forms of exercise to improve core strength. Pilates and Yoga are two of the more popular ones that have been scientifically validated to work. However, there are exercises available for all ages depending on your flexibility and fitness level. Some exercise every day is better than no exercise or heavy exercise in spurts followed by long intervals of inactivity.
