What is the fastest way to burn 500 calories or more?

Wow if I just walk for 90 minutes I'll burn 500 calories? Do you keep a certain pace? How fast should I walk to burn 500 calories in 90 minutes? If I do decide to walk as part of my workout, I'll probably walk outside, through the park or somewhere, not on a treadmill so I can't really tell how fast I'm going. This has always been troublesome for me... I don't have that much space to do complex cardio workouts at home, so dvds aren't the best solution either. After listening to many other opinions I've decided to go with the easiest (and most accessible) advice I got - jumping rope. I read some articles about this and heard other's opinions, they were all stating kind of the same thing - you can burn many calories, up to 700 in a hour. Some said 500... ahm well it doesn't really matter, the thing is that most people seem very sure that jumping rope is a great way to burn calories. And since they're all so sure I got convinced to give it a try. Jumping rope is one of the easiest activities (I can't even call it an exercise! I used to do it when I was a kid!) and it's efficient (they say), so I hope it will help me burn my goal amount of calories. About that heart rate monitor... I'm trying to reach my goal weight without spending much money, that's why I don't even have a treadmill or other equipment at home... I'm trying to make things as simple as possible, to burn calories without spending that much money. I know it would be useful, I would love to have one, but it's hard to find anyway, and it's not actually worth it... My parents wouldn't let me spend that much... They're already annoyed by all the changes and complications my diet has produced, asking them to start buying different stuff will only start other fights... Thank you for your advice! But I'll have to lose the weight without any equipment after all.

An average person burns 100 calories per mile, so if it takes you 90 minutes to do 5 miles, you're probably pretty close. My mom is probably 50-60 pounds heavier than me, and her 3.5 mile loop takes her 60 minutes to walk, she burns 400 calories doing it. You should be working hard - sweating, and at a pace where you can say a few words or a sentence, but not carry on a conversation. If you can sing, you're not working hard enough. You should be only able to say your name & address, then need to breathe for a while before doing it again. If walking isn't getting you there, try doing intervals of jogging in there. Walk 90 seconds, run 60 seconds, repeat. I prefer to spend half the time working out and really bust my butt, so my %max of my heart rate usually goes up to 90%. Some people would rather work out at a lower intensity for longer. Give jumping rope a try. There's no way I could stay interested in it long enough to do it for more than 10 minutes, but maybe you can! Sorry your parents aren't more supportive of a healthy lifestyle. I wonder if they realize healthy eating can benefit them too? Yes, healthy food is a little more expensive (not if you know how to shop, though!) now, but it saves LOADS of money on expensive health care problems in the future. Best of luck to you!
