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).

About Your Core...

An Introduction To The Core

Every muscle in your body relies on your abs, hips, and lower back. Your core is your base - and your center of strength. Here are three things that you need to know about your core:

1. You can strengthen your core without moving a muscle. Whereas most muscles propel you, your core resists movement - for instance, to protect your spine when you twist your torso. So don't be surprised by how hard it is to stay still in your core workouts (especially in the exercises I will be posting for the next 6 days - that's right, a week dedicated to the core). You're conditioning the core to do its job more effectively.

2. Slouching sabotages your six-pack. Training your core helps to correct poor posture. But an hour a week of core work can't compensate for 50 hours spent slumped over your keyboard. The fix: stay tall through your hips and keep your head up and your shoulder blades back and down all day long.

3. Core muscles contract first in every exercise. All the energy you exert originates in your torso, before being transferred to your arms and legs. So a weak core reduces the amount of force you're able to apply to a barbell. When you hit a plateau in presses, squats, or any other strength move, ask yourself if you are training your core as much, or hard, as you should be.
