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).

Ascorbic Acid

Found In:
Light orange juice, frozen deserts, hot dogs, bologna, sports nutrition bars, and supplements.

Used As:
A synthetic (but reduced) form of natural vitamin C, that is used to boost vitamin content and maintain the color of processed meats.

Why It Can Be Bad:
Although it is safe, it is neither nutritionally or structurally identical to natural vitamin C, which also contains vitamins J, K, and P and an enzyme known as tyrosinase. It does however count toward your recommended daily allowance. Excessive doses of vitamin C (2,000 milligrams per day) are deemed adverse and can cause side effects. These side effects include osmotic diarrhea, a type of gastrointestinal distress that could require professional diagnosis and care.

Try Instead:
A variety of colorful fruits and vegetables to meet the recommended daily allowance of 90 milligrams a day. To help put things in perspective, a single bell pepper has 95 milligrams of vitamin C.
