Depends mainly on how many calories you want to burn off. and how fit/heavy etc you are.
Walking, maybe you can push the burn to 450 cals/hour at a decent incline.
depends on lots of factors all of which will change the answer. these factors are:agegenderBMIgeneral fitness levelrunning speedrunning terrain/inclinefor me, running at 6mph I burn 900 calories per hour, so I would have to keep it up for 4 hours to burn 3500 calories, or almost a complete marathon.3500 calories is equivalent to 1lb of body fat
When it comes to burning calories, your heart rate is much more important than what you are doing.If you can reach and sustain the same heart rate for the same amount of time you will burn pretty much the same amount of calories regardless of activity.The actual burn rate will depend on how hard you go at it, how fit you are, what you weigh, what your proportion of muscles are etc.I'll usually do 700-900 cal/hour running, but someone smaller and/or less fit might struggle to hit 600.Someone bigger/fitter/younger than me might hit 1100-1300.
The best way for you to burn lots of calories while running is to run up hills or at an incline. If that is not an option you can also run up and down stairs those provides a lot of burn calories.
Many people are counting calories these days. if you jog, run, skip, hop, or walk you can burn lots of calories.
Lots of exercise, such as walking, jogging, cycling, not-too-extreme sports etc. Chewing gum (sugar-free gum is recommended) can also help you burn down calories.
Ultimately, if you gain weight, it means you take in more calories than your burn off. It could be that what you consider exercise is not be rigorous enough to burn fat (sweating doesn't mean you are burning fat) or that your workouts are too short to burn fat (20 minute minimum on the treadmill, for example), or maybe you eat/drink too much of the wrong things at the wrong times...etc.
Yes, but not so much that you'd burn more calories than you were consuming.
Cross trainer set to max 60 cycles per minute - Job done
Tae Bo, according to one Billy Blanks fan website states that you burn 200 to 400 calories per 1/2 hour. Usually the larger you are, the higher the calories burned (until your body gets used to exercising). Hope that helps. You can find lots of information on this by google-ing "how many calories does tae bo burn".
Hard manual labor burns many calories. In addition, cardio exercise (such as brisk walking, jogging, running, trampolining, cross-country skiing, etc) are good calories burning exercises.
You can go online to find lots of information about how to fix a treadmill yourself. If you go to YouTube you can find instructional videos on how to fix common problems with a treadmill.
Any activity will promote some sort of muscle development. But if you pick exercises with low loads and lots of repetitions - basically aerobic, cardio exercises like treadmill, ellipticals, bicycling, running, swimming etc you get the biggest amount of fat/calories being used with the least amount of muscle development.
