In part 2 of this series with Dr. James Fisher, Brian and James discuss the downsides of cardio and why so many people can’t seem to resist binging after cardio exercise. Learn why cardio is important and useful when done right, and how it can lead to even worse health outcomes if not done properly.

• While improving heart health is great, it’s not everyone’s goal when exercising or doing cardio. Weight loss is another major focus and cardio can certainly help accomplish that.
• When doing cardio and exercising at a low enough intensity we are using our aerobic energy system, and that’s reliant on our fat stores as energy. So it’s easy to think that if you do cardio you will burn fat, but the reality is that anything that raises our energy expenditure and increases our metabolism is beneficial for fat loss.
• Building muscle is great for maintaining a higher metabolism and burning more fat.
• With a low-intensity exercise, we see an increase in our stress hormones, as well as a fluctuation in our leptin and ghrelin levels. These are the hormones responsible for hunger and they regulate how our body replenishes and restores calories. When we do higher resistance training we don’t get the same hunger response. The big problem is that going for a long run or bike ride may feel great, but the following hunger response may undo all the work you just did.
• More movement and more steps in a day is a good place to start, but if you go out and start running, cycling, or swimming you are going to swim against the tide and your body will start to resist your efforts.
• Increasing muscle mass is about increasing the quality of our body composition, and that itself is increasing our metabolism. If you look at the bigger picture, cardio alone doesn’t lay the foundation for long-term weight loss.
• Studies generally show that the weight loss that occurs from cardio and a caloric reduction is 50% muscle, which is probably the worst possible outcome, especially as we age. Whereas if we perform resistance training and pay attention to protein intake the weight loss is almost exclusively fat.
• When people say they want to lose weight, they mean they want to lose fat. We need to do something that allows us to hang on to the muscle we’ve got. Starting with resistance training, and then nutrition, with cardio as a tertiary thought is the best method to achieve fat loss and optimal long term health.
• If we do what it takes to protect our muscle with proper nutrition and strength training, the weight that we lose leads to a better body composition since fat takes up so much space on the body.
• Start with resistance training and nutrition, then add cardio if you feel like it.
• When we think of older adults we think of frailty, despite the fact that they are often lean. The reason they are frail is because they are not carrying a high proportion of muscle mass. If we do resistance training and focus on maintaining as much muscle mass as we can when we age, we are setting ourselves up to be lean and functional as we age instead of merely frail.
• An epoc is Excess Post-Exercise Oxygen Consumption, it’s also known as the afterburn effect. When performing high effort exercise our heart rate is elevated for a time after the exercise is complete but with low-intensity exercise, there is almost no after-effect. The energy expenditure from prolonged low effort exercise is about the same as interval training or resistance training a third of the duration. A 20-minute high-intensity workout has the same energy expenditure as a 1-hour run.

Dr. James Fisher answers the question once and for all, do we really need to do exercises like running, cycling, and swimming to improve our cardio? Find out the truth about cardio exercises and cardiovascular health and why you should get off the treadmill and start doing resistance training right now.

• The fundamental question is “What is cardio?” Even people who have seen the results of the 20-minute routines delivered by the Exercise Coach still wonder what place cardio has in physical fitness.
• Historically people have perceived exercise to be going for a run or what we think of as traditional cardio. Usually this takes the form of long duration and low intensity and focuses on aerobic energy production.
• The accepted wisdom is that cardio is just activities like running and cycling, but the truth is that any activity can become cardio exercise if done at the correct intensity. Cardio also raises the idea that we need to perform prolonged exercise to get the result, but that’s not necessarily the case.
• The trouble is that duration doesn’t necessarily translate to improved fitness. Someone going for a 4-hour walk isn’t going to see the results they would see from an activity with a higher intensity level.
• Cardio activities like running, cycling, or swimming improve our heart health because of the sustained elevation of the heart rate. While that’s true and that process also makes the heart and muscles more efficient, but it’s really the act of having the heart rate elevated for an extended period of time that brings those results and it’s not reserved for traditional cardio exercises.
• It is possible to be fit while still having an unhealthy heart due to lifestyle choices. Studies have shown that it is better to be fit and fat, than unfit. People who are overweight and exercise have better health outcomes than people with a normal Body Mass Index who don’t exercise at all.
• Exercises that we perform that are a high enough intensity and frequency can more than counteract any of the other lifestyle risk factors. There is growing evidence that shows that effective exercise alone and improving fitness is powerfully prophylactic in terms of health and longevity.
• Even if you no longer see visible fitness increases from your exercise, you are still catalysing positive changes at a cellular level and prolonging and improving the quality of your life.
• Traditional cardio exercises are not necessary to become healthy. Strength training exercises have similar results to traditional cardio training with similar cardiovascular health benefits. It also comes with less risk of chronic joint pain.
• Don’t feel tied to an exercise modality. Studies have shown that people have seen increases in cardiovascular health and efficiency with only a simple 12-week strength training program.
• Resistance training is the superior choice because, in addition to the cardiovascular benefits, you also improve strength, bone density, and muscle mass. Improved muscle quality is a jackpot outcome because it has a ripple effect that leads to all of the systems of the body getting better when we optimize the health of our muscles.
