Did you know that at some point in your 30's you begin to lose half a pound of lean body mass every year? If you are inactive, but manage to maintain your weight for 5 years, this implies you have actually gained 2.5 lbs of ...that's right, fat. As we age, our lean body mass progressively decreases if resistance training is not implemented on a regular basis. The human body is composed of fat weight and lean weight. Lean weight consists of muscle, bone, blood, organs, skin and connective tissue, and for the most part it allows the body to perform work. Essential body fat (between 2-5% for men and 10-13% for women) is needed for insulation, hormone production, protection of the organs and maintenance of certain body function. The good news...a basic strength-training program can add 3 lbs of muscle tissue in 3 months.
Did you know that resistance training can play a crucial role in helping preserve bone tissue. A German anatomist and surgeon Julius Wolff (1836–1902) development, Wolff's law, states that bone in a healthy person or animal will adapt to the loads under which it is placed. That is, when the skeleton is subject to resistant forces, like exercise, it responds by laying down more bone tissue, thereby increasing density. On the contrary, individuals subject to prolonged periods of bedrest due to injury or illness, their bones become less dense, making them prone to fractures.
Did you know that water is as important as the oxygen we breath. Water is the single largest component of the body, comprising about 50 to 70% of the bodies. Water has many important functions, including protecting the organs, regulating body temperature, aides in nutrient absorption, serves as a medium for biochemical reactions and maintaining blood volume. Severe dehydration could cause stroke, however excessive amounts of fluid could reduce sodium levels causing hyponatremia which if severe is fatal. Fluid-intake recommendations during exercising: drink 17-20oz 2 hours prior to working out, during exercise drink based on sweat loss (about7-10oz every 10-20mins), following exercise 16-24oz for every pound lost.
