If any fitness professional tells you cardio is bad. Runaway. Quickly. Which you will be able to do because your workout includes cardiovascular fitness. Joking aside, we have an uphill battle in this country when it comes to getting people to engage in physical activity.
When potential clients who have struggled maintaining an exercise program are told not to waste their time doing cardio and that the only way to see results is through extreme exercise programs like CrossFit it can be discouraging and perpetuate all or nothing thinking.
From a behavioral health perspective, I encourage clients who have been on the extreme diet and exercise program roller coaster to engage in activities they enjoy. The best kind of motivation is autonomous.
From an exercise science standpoint, Dr. Len Kravitz’s article “The Physiology of Fat Loss” does a great job explaining how to design a well-rounded cardiovascular program including HIIT and steady state cardio. You have probably seen the article being an Idea member. If not I recommend looking it up : )
