Fitness tip # 1 - Split it up - Instead of spending one hour to the gym, do six 10-minute workout sessions throughout the day. Try some slow stretches, leg crunches or lunges when you get up in the morning, during short breaks at work or while you are watching your favorite show at T.V.

Fitness tip # 2 - Hide the remote - Don't be a channel-flicking couch potato. Ask someone to hide the remote so that whenever you need to use it, you'll have to go dig it out. Better yet, if you are spending more than half an hour parked in front of T.V., use a treadmill or stationary bike while you are at it.

Fitness tip # 3 - Get outdoors - In your leisure times, opt for activities that excite you. Go to the park, walk the dog, plan picnics or do something more adventurous like hiking, rock-climbing paddle boating or scuba diving.

Fitness tip # 4 - Use the stairs - If you are at work or at shopping mall, avoid taking the elevator. Opt for the stairs. Climbing up the stairs adds strength to your leg muscles and gives you a cardiovascular workout. Climbing down the stairs builds strength in the quadriceps and hamstrings. To burn over 200 calories at once, run up and down a flight of stairs as fast as you can. Two at a time if you are particularly brave. Do this every day in five-minute sessions.
