The debate over cardio vs. high-intensity interval training (HIIT) usually assumes that the issue is an either/or choice. In that debate, HIIT is usually compared to absurdly low levels of cardio exercise – not to the kinds of classes ICI-PRO instructors probably teach. This post explores the evolutionary value of combining cardio and HIIT. In his book Born To Run, Christopher McDougall reveals the blend of morphology, paleontology, anthropology, physics,
Do Indoor Cycling Classes really need to be 45-60 minutes – to provide the health and fitness benefits expected by our participants? Asked another way: If your studio offered classes that were shorter (say 30 minutes), while still just as effective as 3/4 or a full hour, could an “express class” attract people who feel time strapped? Of course anytime you use the words “just as effective” smart Instructors are
In a previous post that I co-wrote with Jim Karanas, we described specific physiological adaptations of aerobic – aka cardio or endurance – training. As you may recall, they include increases in blood volume, tidal volume, and stroke volume. The capillary network increases, as well, as do the size and number of mitochondria. Other changes also occur, but these are the ones that move oxygen to the working muscle. Recent
There are times when exercise can be painful*, especially when you’re coaching or participating in, a HIIT or Tabata® training class. You know that. You might also be aware that the more you expose yourself to high intensity training, the feelings of pain / discomfort you experience diminish over time. Said another way; over time, you may develop a tolerance for the pain that accompanies HIIT or Tabata® type training.
