I gotta confess I thought aerobic and anaerobic were about soil health. Oh, sure, I know about aerobics, which are vigorous exercises. C’mon, it makes sense that I wouldn’t associate aerobic and anaerobic with exercise…I hate exercise.

Nor was that the only surprise…turns out cardio is another way to say aerobic exercise.

Aerobic is all about needing oxygen. Aerobic exercise — swimming laps, running, cycling, jogging, etc. — that lasts longer than two minutes and increases breathing and heart rates over a sustained period of time.

Anaerobic is the lack of oxygen . . . in fact the presence of oxygen could kill. Hmmm, not for me then . . . I know…any excuse… Anaerobic exercise includes weightlifting, throwing, sprinting, jumping — any exercise that requires short, intense bursts of physical exertion.

Cardio is all about the heart, so everything that has to do with the heart is cardio including aerobic exercise which gets your heart rate up into your target heart rate — the zone where you burn the most fat and calories. Woohoo! Annnd, vacuuming and mopping, shoveling snow, raking leaves, etc., are all aerobic exercises! I love it when you can accomplish more than one thing at a time!

Word Confusions . . .

. . . started as my way of dealing with a professional frustration with properly spelled words that were out of context in manuscripts I was editing as well as books I was reviewing. It evolved into a sharing of information with y’all. I’m hoping you’ll share with us words that have been a bête noire for you from either end.
