Resistance Training, A Key To Losing Fat.

Resistance training is an efficient form of exercise for weight management. Period. End of story. It is my go-to prescription for clients looking to tone, build muscle, and lose fat. Yet, with the benefits resistance training offers for weight management, why do beginner fitness clients opt for aerobic exercises (cardio) instead, spending hour after hour on treadmills and elliptical machines?

Let’s dispel the common myth and jump into the science behind the benefits of resistance training for fat loss. First, the myth…

Let’s shed some insight into the least regarded exercise regimen among beginner weight-loss clients. Speaking from my professional experience as a physical trainer, one of the most frequently asked questions is: What training is best for weight loss? When I relay weightlifting training as the answer, I’m often met with a look of apprehension. Most in the female demographic seem to have a misconception that resistance training leads to a masculine appearance. A comment to which I would jokingly reply: “Do you mean that resistance training will make you grow a mustache?

To sum up, resistance training converts your body’s energy needs using fat deposits as the source. Reducing your caloric intake and/or the consumption of weight loss products alone can not offer similar results. Why? Stand-alone “dieting” often results in losing vital muscle mass and targeted fat deposits.

Body Composition Test

Physical trainers are responsible for educating the community, mainly beginner weight-loss clients. First, let’s clarify that resistance training helps with fat loss, not weight loss. Before starting any resistance training, conducting a body composition test is recommended. BMI weight scales and calipers register the ratio of lean body mass to fat body mass. After continuous resistance training, it will be evident that lean body weight has increased, and total fat has a dramatic decrease. Remember that total body weight will increase after two weeks of weightlifting training. I know what you’re thinking: “I’m trying to lose weight, not gain weight!”

Regular weight scales register overall body weight and do not differentiate between muscle and fat tissue. It’s a common mistake to misinterpret the number on the scale and/or blame resistance training as being ineffective toward your fitness goals. This circles back to the importance of conducting a body composition test to measure increased muscle and fat loss. Next, I’ll delve into the science that outlines the benefits and effectiveness of resistance training.

Resistance Training, Weighing In On The Benefits (Pun Intended)

I’ll use a cup of water analogy to describe best how weightlifting training works towards lean body development and reducing fat. Think of your muscle energy stores as a full cup of water. During exercise, your muscle energy stores deplete. In other words, your cup becomes empty. It now becomes a priority for your body to replace these empty energy stores. Let’s fill your cup with water. The “water” in this analogy is triglycerides and glycerol.

Here’s the scientific breakdown; While in recovery, your muscles refill the empty stores by converting extra muscular fat (triglycerides) into energy, and it uses fat (glycerol) in the process. Fatty acids from the triglyceride conversion provide the fuel to fill muscle energy stores. Now let’s take the cup of water analogy one step further by adding a gallon of water into the equation. Let’s now take that gallon of water and fill your empty cup. The gallon of water represents your body fat (adipose tissues). Fatty acids and glycerol are extracted from adipose tissue, which repletes muscle energy stores.

To Review…

Resistance training causes fat to be released during the recovery process. Traveling through the bloodstream, these fat deposits are now absorbed by the worked muscles as energy for recovery. Now that we touched on the science behind the benefits of resistance training let’s delve into why an increase in body weight would occur, a topic I mentioned earlier.

Increased lean and total body weight increases due to increased muscle energy stored (glycogen). Muscles are more compact and dense than extra muscular fat (triglycerides). Body fat (adipose tissues) is less dense. Therefore, it occupies more space in your body than muscle. Take, for example, if we compare:

A. toned abdominals

B. a pudgy set of abs.

Which of the two takes up more surface area? If you chose B, you are correct!

In Conclusion…

Muscle fibers are nourished, energy stores are replenished, and fat decreases. Resistance training contributes to increased lean muscle, strength, loss in body fat, and also increases metabolism. So does this mean you’ll go to the gym and bench press two hundred pounds till your arms fall off? This is where the importance of having a certified personal trainer comes into play.

There is a correct and incorrect approach. High repetition, low intensity, long duration, and using basic compound movements are the best curriculum for a beginner and/or fat loss client. The selected exercises must maximize the target muscles to ensure energy storage depletion. Doing so will result in more fat being used to replete muscle energy stores. Continuous resistance training ensures weight management, fat loss, and muscle maintenance.

Remember, the goal is to lose fat, not muscle. Participating in a reduced caloric intake and/or the consumption of weight loss products without resistance training can result in the body cannibalizing muscles for energy.
