Top Five Tips to Lose Weight

Recommanded Answer:
It's not just a matter of how long you run. You speed and style can be just as if not more important. If you make sure you're running at a high intensity, you could get away with 20-30 minutes 4 or 5 days a week.But if you lower that intensity, you may have to up it to 60 minutes 6 days a week. You might also try a style of running called HITT. Stands for high intensity interval training. There are many variations of this, but the principle is that you run as fast as you can for a short period of time and then recover for another short period of time by decreasing intensity to normal. And keep alternating this pattern. You can get away with only doing this for 20 minutes each time you use the treadmill because of how efficiently this style of running burns calories.
Ah and yes, you can't ignore your eating habits either. Losing weight is 80% diet, 20% exercise.

• At LEAST an hour for weight loss and you also need to add in weightlifting for gaining muscle mass a treadmill is cardio which helps loss weight but not gain muscle
• its not how long, its how much. if youre really deticated, you need to do a LOT more than just running. The main thing you need to do is eat right. if you dont eat right, the fat wont go anywhere, and you wont lose weight, no matter how hard you work. run for at least 45 minutes EACH day, and do cardio and fat burning exercises EACH day.
• As long as you can then the next time improve it by a little bit more so your reaching you full compatibility
• 30 minutes at least 5 times a week. Add in weight-training as well to build muscle and trim fat. Improve your diet if needed as well.
• I used to run for 20 minutes with all of my speed.
  It worked.
• From how I understand it, the amount of time you need to exercise depends on how many calories you have eaten that day. All you need to do is exercise enough that day to burn more calories than you consumed. That usually means around a half an hour an hour worth of exercise, but it varies depending on your diet.
• Don't run to lose fat; run as you usually would, as part of a sensible workout plan. 30 minutes 3-5 times a week is plentiful. More fat burning if it is interval training.
  Losing fat is done in the kitchen, not at the gym. Eat healthy, eat less than you burn, you lose.
  The problem with running too much (an hour a day, every day etc) is that it tires you out, and you are bound to get some sort of injuries.
