Is Cardio or Strength Training Better for Fat Loss?

What is the safer, more enjoyable, and more effective way to burn fat? You might think that you know the answer, but do you know why?

This passage has been written after so much confusion , and bullshit from professionals who are biased to a certain side and speak out of there ass, on which is better for fat loss (Cardio or strength training) . I will show that the benefits of doing steady-state cardio for fat-loss (without muscle loss) are often misunderstood and overstated. Then it will offer a solid, commonsense argument for metabolic strength training concepts, which are safer, more enjoyable, and much more effective training option for helping your clients build the lean and muscular body that they want.

Research Confusion

A 2012 study published in the Journal of Applied Physiology looked at the effects of aerobic and/or resistance training on body mass and fat mass in overweight or obese adults. It concluded that, “A program of combined Aerobic Training and Resistance Training did not result in significantly more fat mass or body mass reductions over Aerobic Training alone” (1).

Naturally, these results made the rounds in the media, attached with the claim that “cardio is better for fat loss than weight-training.” But the reason cardio works faster than weight training in these short term studies isn’t because it has special fat burning powers over strength training, it’s simply because cardio burns more calories during the workout than strength training.

And the relationship of how many calories you consume per day to the number you burn per day is the single most important factor when it comes to determining whether you lose fat. Too lose fat you NEED TO BE IN A CALORIC DEFCIT!

As an aside, the idea that you need to be in a caloric deficit to lose fat isn’t personal opinion, nor is it up for debate by so-called diet gurus / or even Physicians who have no real knowledge about the physiology of weight loss, but since they are physicians their word is bond. In other words, it’s not about what this or that person says about nutrition — it’s about what the evidence shows. I only believe in evidence based practice and not the word of people who have no real idea what they are talking about. BUT THAT’S JUST ME !

The research into the potential advantages of diets emphasizing protein, fat, or carbohydrates have found that reduced-calorie diets result in clinically meaningful fat loss, regardless of which macronutrients they emphasize. (2)

Now, this isn’t to discount that some calories are more nutrient dense than others we’ve all heard the term empty calories — but one can still be well-nourished and overfed, MYSELF for example. So as important as it is to eat high quality, nutrient-dense foods, you can still gain fat from eating “healthy,” if they eat too many calories relative to what they’re burning.

So when it comes to doing cardio, fat loss comes from burning more calories than you consume. It’s obvious why cardio works faster than weight training in these short term studies comparing cardio training to weight training for fat loss — because cardio burns more calories during the workout than strength training. However, instead of spending the extra time doing cardio to burn (let’s say) 300 calories, you can simply cut 300 calories out of your diet each day and end up with the same result without having to bother with all the potential side effects and boredom issues with cardio. This is why cardio training isn’t emphasized in the book written , Strength Training for Fat Loss. In most cases, you eliminate the need for it (from a fat loss perspective) when you simply eat fewer calories to create a deficit.

“In most fat loss cases you can eliminate the need for cardio by creating a caloric deficit.”

In other words, you essentially eliminate the need for doing cardio (from a fat loss perspective) when you simply eat fewer calories to create a deficit. But this all dependent on my patients medical history. Cardio can be very important function of improving a pathological patients exercise capacity.

The Negative Side Effects with Cardio

The problems with steady-state cardio for long-term fat loss are the negative side effects of the two most common cardio training methods, jogging and cycling. Both training modalities are effective forms of exercise and are nice ways to get outside and do something active, but there are major drawbacks to doing them regularly.

Both jogging and running (jogging is a slower run with a shorter stride) can be tough on the joints (even with proper strength training) because each step you take brings an impact force of about two to three times your body-weight. The impact force results from an abrupt decrease in velocity of the foot as it contracts the ground. In a 30-minute run, a typical runner will have about 5,000 impacts, so the accumulation of them are likely the root of the injury problem.

The impact force and the ensuing impulse wave have been identified as potential factors in injuries such as stress fractures, shin splints, cartilage breakdown, low back pain, and osteoarthritis (3). Furthermore, most of us sit too much during the day. At work many of us sit at a desk, and at home we sit while using the computer and watching TV. It’s no secret that sitting (i.e., being sedentary) isn’t the best thing for functional capacity (our movement ability and athleticism), but physical activity is great for helping us get lean and increase strength and performance.

Although cycling is physical activity, it’s done from a prolonged sitting position where you’re hunched over the bike. So you’re not only sitting all day at work and at home, but when you work out, you’re sitting again! Furthermore, cycling gets your body better at cycling — it doesn’t do much for strengthening your muscles for day-to-day activities. This isn’t meant to convince you to quit running or cycling, especially if you enjoy these activities. It’s simply to inform you of their limitations and risks.

The workout programs in the book, Strength Training for Fat Loss provide a tremendous metabolic training effect without the impact on your joints that comes from running or jogging. In addition, the workout protocols are designed to fight the negative effects of sitting by training your muscles in more athletic postures and more dynamic movements.

The Verdict Is In: Strength Training + Diet = Fat Loss Without Muscle Loss

Although any type of physical activity can have positive health benefits, the benefits of steady state cardio from a fat loss (without muscle loss) perspective is often misunderstood. Research like the type mentioned above only adds to the confusion.

The facts are:

1) You don’t need to bother with all that boring cardio (to burn calories) when you simple eat less calories to create a deficit, but the problem is most people under estimate how many calories they are actually consuming

2) You don’t just want a “lean” physique — you want a lean, strong and athletic-looking physique. To achieve the “strong and muscular” part, you’ve got to do resistance training, which is why the researchers of these studies usually say that a program including resistance training is needed for increasing lean muscle. There’s weight loss and there’s fat loss. When people say they want to lose weight, they mean they want to lose fat, because you certainly don’t want to lose muscle as muscle creates the shape of your body. So when women talk about “toning,” “enhancing,” or “shaping” certain areas of their body, what they’re really talking about is muscle, as you can’t build a perkier, rounder, or sexier anything without building muscle. In short, if you’re looking to lose fat, go with metabolic strength training concepts as your primary form of exercise. Watch your diet (instead of doing lots of cardio) to reveal your shape, and strength train to improve that shape. The only type cardio clients should be doing is high intensity i.e. between 65%-85% Vo2 max for 4 minutes and 1 minute above 85% of  v02 max.  This type of workout protocol on a treadmill , elliptical, Stairmaster, bike will allow clients to work above there anaerobic threshold . This will allow the patient become ischemic and when a patient becomes ischemic there are many benefits for there physiology. If you do not know these benefits , you are not qualified to work with these special populations and should go open a book before doing any  more damage to a client.
