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).

3 Things You Probably Don't Know About Your Biceps

3 Things You Probably Don't Know About Your Biceps

1. The visibility of your cephalic vein, which runs across your biceps, has nothing to do with how many curls you can perform.
To make this vein pop, you need to drop your body fat below 15 percent. Don't be surprised if the vein is more pronounced on one arm than the other: Genetics also play a key role in determining its prominence.

2. Under a microscope, some muscle fibers look pinnated, or feather shaped. But the biceps' long parallel fibers give them the ability to bulge.
This means that devoting just a little attention to your biceps, especially compared with other muscle groups, goes a long way toward making them grow.

3. The average guy's biceps are composed of about 1 pound of muscle.
For both of your arms combined, that's just 3 percent of the amount of muscle mass in your entire body. Remember that number: It's a good way to keep a perspective on how much you train your biceps compared with your other muscle groups.
