Why Weight Training

Why does Time for Change Fitness promote resistance training?

Many people focus on calories alone. The slash and dash mentality develops destructive patterns, like extreme calorie cuts and/or excessive aerobics. This sets off an alarm-state in the body where the body sheds muscle tissue to lessen energy demands, and stores body fat as a survival response. Once this physiological state is reached, it becomes nearly impossible to lose any more weight no matter how many calories you cut or how much aerobic work you add. What you end up with is a person who is on a starvation level calorie count and performing excessive exercise, yet is still flabby.

The calories burned during an exercise session are relatively small compared to the amount burned during the other 23 hours of the day. Most fat oxidation occurs between training sessions, not during. This means your exercise sessions should primarily be geared towards building muscle and boosting your metabolism.

After a strength training session, the metabolic rate raises (the after-burn effect) for longer periods of time than after aerobic work (up to 48 hours). This is because all of the steps involved in the recovery process from strength training (satellite cell activation, tissue repair, protein synthesis, etc.) require energy (calories).

L-Glutamine

L-Glutamine: Produced by the liver, this is the most abundant amino acid in the body. It has been shown to support the building and maintenance of lean muscle tissue and has been used in hospital settings to promote overall health and repair the intestinal tract. The use of glutamine has been correlated with increased fat metabolism and improved mental clarity. It is used by the brain to manufacture neurotransmitters. Since we have the same neurotransmitters in the brain as in the colon, some claim it only makes sense that improving colon function will also increase brain function by helping the body to deal with mental and physical stress. In addition, glutamine has also been shown to alleviate blood sugar problems by decreasing insulin resistance. Olympic strength training coach Charles Poliquin uses it to help his athletes accelerate muscle glycogen resynthesis after exercise without elevating insulin levels, thus helping them to lose body fat.
