what is aerobics


Aerobic: This word, by itself, simply means "with oxygen," but it comes alive when used as an adjective to describe exercise. Aerobic exercise is exercise that is vigorous enough, lasts long enough and is done regularly enough to keep your heart and lungs in good shape. Aerobic exercises burn fat faster than any other type of exercise.
From Jacki Sorensen's Aerobic Lifestyle Book by Jacki Sorensen with Bill Bruns.

Exercise: You know what this is. The official definition according to Webster's New Collegiate Dictionary is "bodily exertion for the sake of developing and maintaining physical fitness." Notice that there's nothing in the definition that says exercise needs to be boring, cumbersome, or repetitive. We're here to tell you that you can achieve physical fitness with exercise that is fun and enjoyable
Fitness: Here's what fitness means to Jacki Sorensen: a firm, lean body; a strong heart; a slower heart rate; lower blood pressure; muscle strength; muscle endurance; flexibility; and the most magic ingredient of all: energy. Fitness...makes you feel so good; so truly alive!

Abs is short for "abdominals." A lean, flat stomach requires strong abdominal muscles and the elimination of abdominal fat. Because it's not possible to effectively strengthen the abdominals without lying down and working against gravity, every Jacki's class includes a concise abdominal routine on the floor.

Gluts (pronounced "gloots"): "Gluts" is short for "gluteus maximus" (large muscles of the buttocks). These muscles receive special attention when we do "glut work" during the Vertifirm™ segment of class.

StrongStep™, Jacki Sorensen's newest aerobic program, is a unique blend of exercise, bench, and resistance training using a step for increased lower-body resistance. StrongStep is a total-body workout of low-impact, high-energy step routines. For more information about StrongStep and Jacki's other aerobic programs, see Jacki's Aerobic Programs.

Vertifirm™ stands for "vertical firmness." Vertifirm is Jacki's system of firming muscle groups while standing up, instead of in traditional floorwork. Because traditional floor exercises only work on isolated muscle groups and do not significantly raise your heart rate, they are not effective fat burners. Jacki has taken these exercises off the floor and choreographed them so you get the muscle strengthening and toning of floorwork combined with the calorie-burning capabilities of aerobics. Students may use optional hand-held and ankle weights during the Vertifirm segment for additional muscle strengthening and toning. (Ankle weights are not used in StrongStep™ because the step provides enhanced lower-body resistance.) For more information about Vertifirm, see What Is Vertifirm?
