The Maggie's Fitness for Life program includes about a one-hour session of aerobic endurance exercise per week. For true cardiac exercise, we include plenty of HIIT cardio whether in calisthenics or sprints. That tends to be anaerobic.
Why do we include the endurance work at all? For ordinary functionality. We figure that if you can swim for an hour, or do the stair machine or high-inclined treadmill for an hour, well then a 6-hour hike, a day of skiing or basketball ought to be manageable. We strongly oppose road running.
So pure endurance work is only about 15% of our program although we assume most people also do fun recreational things like sports or hiking which do not count as exertion. Mark Rippetoe has other ideas. He is convinced that endurance exercise is a waste of time, and sometimes deleterious.
He is a smart guy, and might be right. Our Maggie's program attempts to strike a balance between strength-building (2 hours/wk of powerlifts and accessory weights), calisthenics (athleticism, balance, agility, HIIT, some strength), and "cardio" (an hour total of HIIT intervals with good rest intervals, and an hour of strenuous but aerobic endurance things). No need to do the hour of HIIT, for example, at the same session. In fact, not a good idea. Mix and match 1/2 hours of different categories but if doing weights, always do them first.
Most fitness trainers consider an hour of endurance work as a "recovery day," but I do not. For me, a half hour on the Stairmaster and a half hour doing high incline walks and jogs on the treadmill leaves me limp for a while.
Final word of 2019: Exercise for fat loss is nonsense. That is 99% nutritional. However, exercise does reduce appetite.
