57. Move those feet! Fitness experts say grown ups should take at least 10,000 steps every day—that equals about 5 miles of walking. It's good for kids to take even more than that. Here are some good ways to sneak in more walking: walk around during commercials while you’re watching TV, dance when you clean your room, jog in place while you talk on the phone, etc.

58. Start your own team. You don’t need to be on a formal team to play sports. Get together with friends as often as you can to shoot hoops, kick around a ball or play Frisbee. The important thing is to get moving!

59. Little kids have tons of energy, so the next time you have to entertain your little brother or sister, make it fun and healthy for both of you by running around and playing games instead of watching TV.

60. Being outside in the cold weather can give you lots of chances to make your body stronger. Try playing tag in the snow, sledding or having a snowball-throwing contest (make your target a tree, not your little brother.)

61. When the temperature soars, let water be your best friend. Drink lots of it so you don’t get dehydrated. And play in it by washing your family’s car or running through a sprinkler. (Just don’t drink the water you used to wash the car!)

62. The woods can be a great place for adventure. Take a family hike and turn it into an obstacle course. Scramble over rocks, jump over streams and shimmy under branches.

63. Kids should be active for 60 minutes every day, but you don’t need to jam all that activity into the same hour. Take the 10-minute challenge: See how many times a day you can be really active for a 10-minute period. What’s active? Dance, jog to a friend’s house, rake leaves, vacuum like you mean it, jump rope or do jumping jacks. All those 10-minute activities add up to a lot of good exercise for your body.

64. Practice makes perfect. The next time you’re by yourself, turn off the TV and entertain yourself by practicing something you’ve wanted to get better at. Shoot 25 foul shots, hit tennis balls against a back wall, do cartwheels on a line, time yourself doing sprints, etc.

65. Feeling blue? Shake your tail feather. Exercise gets more oxygen to your brain, which makes you feel good. Plus, once you start moving around, you start to concentrate on what you’re doing, which helps you forget what was bothering you in the first place.

66. Woof! To make your best friend happy, and get in some more steps—walk your dog! You’ll both be happy. If you don’t have one—ask if you can walk a neighbor’s.

67. Ready, set, clean! Next time Mom or Dad asks you to help clean the house, turn it into a workout by moving quickly from job to job and cranking up the elbow-grease factor. You’ll get done faster, get some great exercise and make Mom or Dad happy.

68. Don’t be a couch potato. If you’re watching TV, do something active during every commercial – jumping jacks, sit-ups, push-ups or lift light hand weights.

69. For fun and exercise in the fall, rake leaves into a big pile. Find a friend and jump into the pile. Repeat. Then stuff the leaves into giant pumpkin-shaped bags and make your house look great for Halloween.

70. There’s power in numbers, so grab a friend to play an active game or walk wherever you need to go. You’ll be more motivated to keep moving if others are involved.

71. Stretch like a cat to prevent injuries. When you're flexible, you can play harder without having to worry about getting sprained and strained muscles.

72. It's easy to find things to do for good flexibility! Gymnastics, yoga, ballet and martial arts all make you stronger and more flexible. Plus, they’re really fun.

73. The wintertime is loaded with ways to get fit and healthy without even leaving your yard. Shovel the driveway, construct an igloo, build a snowman (then change its clothes daily to amuse the neighbors).

74. Rolling, rolling, rolling… The next time you’re looking for something fun to do, strap on some inline skates, take off down a paved path, and sculpt some great lower-body muscles. Be sure to take a friend with you – you’ll both work harder and have more fun.

75. Feeling a little sore from a tough practice or dance class? You’ll feel better quicker if you do a light workout rather than rest completely. A light workout increases blood flow to the sore area, which helps it heal.

76. Variety is the spice of life, so if you’re bored with your routine, try hitting the local library for new videos or DVDs to learn a new activity such as dance, yoga or even martial arts.

77. The stair challenge: Any time you see stairs, take them – you’ll strengthen your leg muscles and get a bit of a cardiovascular workout. Challenge yourself to climb them quickly, or two at a time (or both!)

78. To keep your back healthy and strong, practice good posture, do sit-ups regularly and pick up heavy items by squatting down, not bending over.

79. Cool it. Make sure you take the time to cool down with light exercise or stretching at the end of your workout. It prevents you from getting dizzy, and keeps your muscles from feeling sore the next day. Your cool-down is also a good time to stretch.

80. If you want to play better during a game, it’s a good idea to warm up first with some light exercise. Light exercise (such as a slow jog) makes your muscles warmer and more flexible, which makes you quicker and less likely to get hurt.

81. Brrrrr—it’s cold outside! When playing or exercising outdoors in the winter, you want to stay warm, but don’t dress for a week at the North Pole. Instead, wear layers you can peel off as you warm up.

82. Head for the hills. When snow falls, strap on some cross-country skis with your family and hit the trails. Cross-country skiing works your heart and lungs and nearly every muscle in your body. Plus, it’s affordable and the scenery is great.

83. Set goals. You’ll stay more interested in getting fit if you set goals and then reward yourself as you achieve them. Start by asking yourself what you want to accomplish, and then come up with a plan for how to do it. Let’s say you want to make the soccer team. Your plan might include learning to keep the ball in the air for five minutes without using your hands. When you reach a goal, first reward yourself (download some new tunes to work out too!), then set a new goal.
