work out 3 days a week keep your heart rate elevated for 20+ minutes. Eat a sensible diet and you should be fine.

There's too many x-factors with a question like this to offer effective advice.  No idea how fast you are now, how healthy your present lifestyle is, what monetary resources you have to sink into this goal, etc etc.\n\nThat's especially true because 2:50 over 800 meters is a pretty fast time for a non-elite runner.

It's ok to workout a few days in a row, as long as you are training different muscle groups each day. Do not workout everyday of the week, you need days off so the body can recover.\n                  good luck....

No problem!  Change your diet a little.  If you don't drink water, go ahead and start instead of drinking caloric drinks.  Go walking veryday.  This is really simple!  If you want, you can jog 5 mins, then walk 5 mins and keep doing this until you are able to jog 20 mins straight.  You can do it, but I bet just drinking water and walking will be enough.  Eat more veggies and less saturated fats!  Good luck!

Yes, you can split up the exercise.  The key is to do at least 20 minutes at a time.

You should be OK, listen to your body you may want to cut it a little shorter than 18 miles.If you have been running you really should be OK\n\nPS you might want to ask this question in Diet and Fitness. Most of us runners seem to be there more often than sports.

Assuming you're jogging the recommended 20 minutes at a slow to moderate pace, roughly 2 miles.

Essentially, you should probably change your routine to twenty minutes a day, four times a week.  You need to give your body time to warm up and let your heart rate pick up a bit.  Good for you for doing fifteen min. per day though!  When most people start a new exercise routine in conjunction with a good diet, you should begin to see slight results within three to four weeks.  After that, it will happen like rapid fire if you stick to your routine.  Good luck!

yes this is fine - but it is preferable that you are spreading your exercise out and not doing 4 days straight of exercise and then 3 days of nothing. It is good to have a good workout 1 day and a rest the next and then another good workout the 3rd day and so on.

If you're going to the gym anyway, then I'd recommend cutting back on your cardio to maybe 30min each visit (but make sure you're working hard enough to sweat profusely), and replace the other 30 minutes (or so) with weights (30min) and stretching (5min or so).\n\nFor the cardio portion, consider 2 machines for 15min each, but skip the cycle entirely.  go with treadmill, rowing (if available), and elliptical.  Do the elliptical or rowing first, and 'warm up' for the first 5 minutes.  5min 'cool down' at the end is plenty before you move on to the weights.   The stretching at the end is when you completely cool down.\n\nCheck out "Hot Point Fitness" for suggestions on all specifics for cardio, weights, stretching.

Many experts say that if you walk 30 minutes a day at a brisk pace you can remain fit.  Some walk 60 minutes every other day.  Walking more may help burn off excess calories to get fit while it takes less walking to remain well toned.

Probablly the jog, but you could mix it up into intervals.  RUN for 60 seconds then walk for 60.  20 minutes of High Intensity Interval Training has shown to be more effective than an hour "in the fat-loss zone"

Approximately yes.\n\nYou'll burn about 20 to 30 calories more by running 2 miles in 20min, which is very negligible.

Alternating is a great way to go. You walk for one minute, and jog for one minute, then walk for one minute, and run for one minute.\n\nAt first you may need to build up so, try walking for three minutes, and running for 45 seconds, brining the times closer until you can do one for one minute, and the next for one minute. Then, build to two minutes, and so on.

Like any other muscle, your heart & lungs can use a break every now and then too.  I'd keep any HEAVY running to a maximum of 5 times a week.  Light jogging can be done daily however.
