Aerobics, programs of physical exercises that help people improve their level of fitness by temporarily raising their heart rate and breathing rate. The term aerobics—the original name for the activity—is now somewhat outdated, and most enthusiasts use the name group fitness or group exercise.

The health benefits of aerobic exercise are numerous. People who regularly attend classes can improve their cardiovascular health, reduce their body fat, increase their flexibility, and strengthen their muscles. Other benefits include increased energy levels throughout the day, decreased blood pressure and cholesterol levels, a strengthening of bones, improved posture, and a lower level of stress.

Below are 5 of the most common forms of aerobic exercises that you can do with ease.

1. Aerobic Exercise – Walking

Walking is one of the most common aerobics exercises performed today. Anyone can walk at least a short distance and since many people walk on a daily basis, it’s not an exercise that requires a special skill. The main cons with this exercise routine is that in order to burn a lot of calories, you will need to either walk many miles or you will need to walk at a very fast pace.

2. Aerobic Exercise – Running

By turning that walk into a slow jog, you can burn more calories in less time, while also improving your heart and lung strength more quickly. Running is something that can be harmful to those who have weaker knees or back problems, so working with a coach on your form is the best way to begin if you’ve never run before.

Also, it’s a good idea to make sure you’re not running too quickly at first, especially if it’s been a long time since your last workout.

3. Aerobics Classes

If you like variety in your workout routine, aerobics classes are a good choice for you. With everything from dancing to boot camp workouts, you can find something that suits your tastes as well as your current skill and fitness level. The main concern with aerobics classes is that if you don’t have a qualified instructor, you might be at risk of performing a movement wrong and becoming injured. Also, make sure to look for classes that offer adaptations for participants of all fitness levels.

4. Aerobic Exercise - Biking or Cycling

Whether you like to ride a stationary bike or you like to hit the road, biking is a low impact and fun way to burn calories and get into shape. Safety is a big concern when you are biking, so be sure to use a helmet whenever you are on the road.

5. Aerobic Exercise – Swimming

By providing minimal resistance and impact, anyone can swim in order to get into shape. You might want to look into water aerobic classes in your area to make sure you are boosting your heart rate as much as you can safely.
