5 aerobic exercises to keep you fit and having fun

You've probably heard a lot about the benefits of different aerobic activities, but no one form is inherently better than another. Here are some popular exercises and what they have going for them:

• It doesn't cost anything, won't beat up your joints and you can do it virtually anytime and anywhere.
• Walking's low intensity makes it a good starting point for any exercise program.
• If you pick up the pace, especially on hills, it delivers a solid cardiovascular workout.

• Jogging is almost as inexpensive and convenient as walking.
• Because it's more intense than walking, you can get a good workout in less time.
• It also feels more serious than walking, which can bolster your sense of accomplishment.

• Cycling delivers so many fitness benefits, plus a bracing rush of speed — at least if the bike is real, not stationary.
• Bicycling is also about the journey — you can cover a fair distance, pack a lunch and make it an adventure.
• Cycling exercises your heart and your leg muscles without putting undue stress on your knees or feet.

• By taking the load off joints, swimming is one of the exercises least likely to injure you, especially if you're overweight.
• It's also highly aerobic, depending as much on heart and lung capacity as muscle power.

• Not only does dancing provide the aerobic benefits of jogging, but it improves your sense of balance and stretches your muscles.
• Plus, it's a lot of fun.

Your main goals in aerobics is to move your body, pump up your heart rate and have fun doing it. What you choose is a matter of preference, though some aerobic activities may be more appropriate for you than others.
