myth Because the abs are endurance muscles, you have to do hundreds of reps to get results.
truth Abs do have greater endurance than most muscle groups—however, "doing an exercise with proper form, using slow, controlled motions, is an excellent way to maximize results," says Stuart Rugg, Ph.D., chair of the department of kinesiology at Occidental College in Los Angeles. If you're using correct form (see "Ready, Set, Crunch!" at right), there should be no reason to exceed two or three sets of 25 reps of any ab exercise you do. "Quality is more important than quantity," Brungardt adds.
