How fast will it take your tummy to get flat you run one mile to and 1 back twice a day and do 100 crunches a day?

Answer 1

Of course, it depends on how far it is from flat right now. On level ground, it takes about 100 (varies some with your weight) calories to go a mile at any speed. According to your fitness level, walk faster or up hills, and you'll burn more calories in the same amount of time. There's not a lot of good info on crunches, but I've seen something like a calorie a crunch, so we'll go with that. Assuming you've added these to your daily routine, with no other changes, that means you're burning an extra 300 calories per day. At 3500 calories per pound, you'll be losing a pound of fat every 13 days. The crunches will be firming up your abs, but they'll be hidden under a fat layer until you've lost the excess weight. And remember, you'll be losing it all over including internally. You can't make fat burn in just one spot. Your abs take their energy from all over, not just from the fat on top of them. If you're not carrying a fat layer, and your tummy just looks fat from poor muscle tone, you'll start seeing some improvement in a week or two. Again, it's just a question of how far you have to go. I've said all this without mentioning changing your diet. If you can reduce excess calories, you will lose weight faster. The difference between the calories you take in and what you burn is weight loss, at the rate of a pound per 3500 calories. If you try to do it too fast, though, you'll lose muscle as well as fat, and that's not good. A pound or so a week is a sustainable rate. For help with calorie intake and good food selection for nutrition, I really like the new USDA food pyramid. Check it at MyPyramid.gov.
