It only took 15 minutes

The beat goes on. . . The debate has continued for decades and I don’t know how many other ways to say it but traditional long, slow, boring cardio is not magic.  CrossFitters know that but many people and trainers don’t.  It’s easy and it’s relatively low risk but it’s a waste of valuable  time.  The results are minimal and can often result in overuse injuries.  The latest research from McMasters University suggest 20 minutes of intense activity 3 times a week is about the same as 2 hours of moderate exercise 7 days a week.  High intensity CrossFit works tremendously for those that want to lose weight as your body continues to burn calories during recovery not to mention the hormonal response.  It’s intensity, not duration that’s most important for maximal fat loss; as well as increased lactic acid threshold and improved cardiovascular function.  So save yourself some time and improve your results by upping your intensity.
