Off or on cycle cardio is cardio!!

You need you keep your cardio at low-moderate intensity (50~70% of your MHR ). This preserves muscle doing cardio at a higher intensity burns off too much muscle

Fasted AM cardio is what I found to be most effective at burning fat.

Favorite piece of cardio equipment is that big step machine. The one that has the endless rotating stair case.

If cant get on that, I use the threadmill on full incline (No leaning back.. Defeats the purpose of the incline)
