Each of the 4 body elements plays a vital role in our health. We want each of the body elements to be in proper proportions: strong bones and muscles, a relatively low percentage of body fat, and appropriate levels of water.
Strength & Flexibility
True strength requires flexibility, therefore you need to both build muscle and stretch your muscles.
Building Muscle

• Adding a few pounds of muscle can increase your metabolism, or at least help make up for the decrease in metabolism that occurs naturally as we age. Unfortunately, as we age, we lose muscle strength unless we build it on purpose.
• Because the body is made up of interconnected systems, having strong muscles strengthens bones, too. Stress on your bones stimulates the growth of bone tissue and that helps prevent osteoporosis. If you lift more weight, you put more stress on your bones, thereby stimulating their growth. People lose bone density as they age so, as is the case with muscle strength, unless we build it on purpose, we lose it.
• Stronger muscles are safer muscles. If you’re strong overall, your balance is better.
Flexibility

• Flexibility is how far and how easily your muscles can move a joint. Like bone density and muscle strength, flexibility naturally decreases as we age. Tendons tighten and joints stiffen. Increasing your flexibility will improve your posture and make it easier for you to move about.
• Increasing flexibility can even fix problems you aren’t even aware of, such as muscle imbalances (such as the front of your thighs being stronger than the back). The imbalances may not seem like a big deal in the short term, but over time it can lead to an injury, such as a pulled muscle.
• Improving your body’s flexibility is an excellent investment in your well being, both now and through the years.
