I'm 175 lbs. 5'10, 23 yrs old from what I've heard my weight is average, but I have a belly. So far I've started running 2 miles a week, I'm guessing I'd have to increase this because the tredmill says I'm only burning 100 calories a mile. I'm also wanting to work on my abs and to do that, I'd have to lower my weight.

Hola...

First off, don't really listen to the treadmill because it cannot tell you what extactly you are burning. They just take your weight, age, and speed and it calculates a rough estimate.

Think for a second... Who will burn more calories, someone running at @ 2 mph or @ 6 mph? You don't necessarly need to run more miles, you could run faster and save yourself sometime. Try keeping your heart rate at about 70-80% of your maximum heart rate.

If you want to try something different, you could do interval training, which most newer treadmills have. Interval training has been showen to help people with their weight. With treadmills there will be variation.... One type will speed up or the other type will incline more... but the idea is that you would jog for 1 min and then sprint for 30 sec... (each machine is different)

how many days a week do you think I should get on the tredmill?

at least 3 to see decent results. Also, to simulate outdoor running, you should put the treadmill at a 1% incline.

I've been running for two years now... i am 5'6'' 165lbs.. started running two years ago combined with weight training... i use to run for 20mins at speed of 6.0 ... incline of 2.5.. after 20mins.. it was around 2 to 2.5 miles... then i would go workout on weights... did that for a year.. lost about 3lbs... 2nd year... i ran every other day... because my knees started to ache... but i started to run at 30mins... with the setting on weight lost.. it goes with peaks .. sometimes instead of treadmill i would do the stair climber... with variable and aerobic mode... i did notice more improvement in losing fat.. now i am at 165lb... but still got a gut.. .. and alot of skin.. i can pinch an inch of skin everywhere... how can I lose it?

i also thin 5.11 165 i have a small belly how can i lose my belly without losing weight all over im top thin to lose it anywere else

talk about old revival....how exactly are 5 yr old posts like this found exactly? haha

Well if you want to work on your six pack, your going to have to loose fat not just weight, fat. It takes time, patience and consistency.
If you don't want to be on the treadmill that long but want to burn as much fat as possible look up HITT http://training.fitness.com/interval...ned-18503.html
You would also have to go on a calorie deficit of about 500 cals a day.

Also continue lifting weights and eat right to minimize muscle loss.
