As a veteran of group fitness classes, you probably have favorite instructors. But if you have always been a solo exerciser and want to expand your fitness regimen by trying a class that is new to you, keep an eye out for these signs of savvy group fitness instructors:
They watch the class: If the instructor spends more time looking at himself or herself in the mirror than moving around the room and adjusting the participants' technique as needed, then look for another class.

• They explain the moves: An instructor who says "watch me first" is a good one, especially in a yoga class, which often involves a series of movements to enter a particular pose. In addition, good instructors will tell you where you should be feeling a stretch or a muscle working. They will use words that you can understand while also teaching you terms for the exercises that you're doing.
• They check on you: Good instructors will ask whether anyone is new or has any injuries at the beginning of a class. This is important because a good instructor can show you an alternative exercise or pose, and help you take part in the class as you recover from an injury.
• They make it fun: Instructors are people, too, each with his or her own personality. If you thrive in a more intense class, or prefer an instructor who is more supportive, it may take some trial and error to find the right fit. The class should become an enjoyable part of your overall fitness plan, not something to dread.
• And last but not least, good instructors are certified by a reputable association in the specialty, whether it is aerobics, spinning, yoga or martial arts.
