Specially the running. Swimming is a good way too. :)
No but it is good cardio and will burn some calories
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.
A running machine causes less joint stress and lower impact, which could be good for someone recovering from a injury. Many running machines also come with arms, which help burn more calories then regular walking.
It depends on your speed & your weight. If you walk at a distance of 1.4 ft per second brisk pace or 4.2 km/hr, you would burn about 218 calories in 24 minutes or 354 calories by walking a total of 1 km. Good luck in your exercise.
Walking is recommended by many health care professionals as a good way to strengthen your feet and ankle muscles before attempting any sort of distance running. In short, any aerobic exercise is healthily; while running will burn more calories than walking given an equivalent time, it's no good if injuries prevent you from furthering your exercise plans.
Running is cardio, and cardio is very good exercise. Celebs now a days do this a lot. Running can burn 500-1000 calories but other exercises are good to do also.
You can calculate the amount of calories you burn when you walk by the amount you weigh and how fast you're walking. The faster you walk, or if you run, the more calories you will burn in the same distance. Here is a good site that can help you calculate based on your speed and weight: http://www.everyday-sports-nutrition-for-women.com/calories_burned.html
The number of calories burned per hour when running will depend on how fast you are running, your current weight and even such things as the terrain. You are going to burn a minimum of 472 calories and hour and could burn as much as 1675 calories (and possibly more). A couple of good charts can be found at http://www.nutristrategy.com/activitylist3.htm and http://www.mayoclinic.com/health/exercise/SM00109.
No it is not the best exercise in my opinion is running and or walking if you find that boring there is always biking. Oh and also i really good weight loss exercise is rowing you burn tons of calories doing rowing. Fact ;)
it is not bad to burn calories because if you do it is good but if you don't burn any than the leftover calories will turn into fat
That really depends on a persons body. there are many factors that come into play when it comes to burning calories. Size weight, and overall health can make quite a differance in burning calories wether walking or running.
Elliptical trainer machines are very good for people with joint problems as it reduces the stress put on your joints. They burn just as many calories as running and more than walking while being safer and better for your body.
