the workout
Gone are the days where all participants wear striped leotards and do leg lifts. Today there is an aerobics class for every age, size and style. Variations such as kickboxing and step class have emerged, but die-hards still find solace in the choreographed original. You burn loads of calories and whip your heart and lungs into shape while having a great time.

upside
A good class is like a fabulous party. You can’t stop dancing and you find yourself drenched in sweat even if you’ve previously hated exercise.

downside
Classes offer generalised instruction rather than one-on-one training. If you are a serious athlete or a couch potato, it may be difficult to find a level to suit you. Regular repetition of movements may be boring and could increase your risk of injury. Just make sure you know your limitations and the demands of the class before you take it, especially if you’ve been injured or have any medical conditions.

requirements
Gear: comfortable and cool clothing, a water bottle, cross-training or aerobic trainers that provide good ankle support.
Instruction/Facilities: make sure the studio is roomy and the floor is springy. A workout room with mirrors is great because you can see whether or not you’re using proper technique. Never do an aerobics class on concrete, as it puts too much pressure on your joints.
Time: 45 - 60 minutes.

the pros say

• Find an instructor and particular style of class that you really like. Seek out a teacher that is aware of the fitness level of people in the class and structures the workout accordingly.
• If you’re a beginner, inform the instructor that it is your first class and let them know if you have any pre-existing medical conditions or injuries. Don’t worry if you can’t do all the moves your first time around.
• Even if you do aerobics, you’ll still need to create a balanced workout program by including strength training, a variety of other types of aerobic training and some flexibility work.
