cardio is great for that. and yes a hour is fine, you only need 30 minutes of elevated heart rate a day for good health. but if you can do the hour keep it up good work.

All good advice!  Also: Be sure a majority of your workout is cardio (moving & sweating) Your cardio needs to be at least 30 minutes hard and heavy!  Watch and cut back and then completely off of these things: cheeses, sweets,soft drinks,fast food, and finally snacking at nite on anything but fruits and salads!  Drink plenty of water. Hope this helps some.....

40 minutes of cardio and some light weight work.  Also watch your food intake, plenty of protiens and good carbs.  Also be sure you drink plenty of water.

you should boost your cardiovascular system--and condition it so you have more endurance\n\ndo this by running on an inclined treadmill\nstart easy at first since your heart isn't at that level yet--and slowly work your way up--so you can run consistently for 20 minutes or so\n\nthen get back in the pool to see your cardio conditioning progress\nyou'll notice significant results! \nmake sure you learn how to pace yourself

You should intake a strict amount and burn more than you intake. Your days off will compensate for muscle growth/maintenance. As far as reps, alternate between reps of 15 and then sets of reps that are no more than 5 (not including warm-ups) on alternating workouts.  The ellyptical crosstrainer has been my favorite for cardio. If you start losing ground on a weightlifting basis, cut your cardio accordingly. Good luck

I don't know if I get runner's high, but after doing about 45 minutes of intense cardio (can be on the treadmill), I do feel those endorphins kick in.\n\nYou have to do more than 20 minutes and you have to be up in that cardio range (usually the treadmill has a chart right on it to give you a rough estimate of heart rates).  Keep your heart rate up at that cardio level for at least 30 minutes consistently and you should start to flow into that endorphin state.  It lasts for a while after you finish, too.  I have to jack up the treadmill to a steep incline to get my heart rate in the target zone.  If you are in good shape, you will have to do that too or your heart will never get the workout it needs and you won't be in that cardio zone.

yeah but are you getting you heart pumping. walk faster, you should do 2 miles in that 30 minutes.  cardio is a fat burner!! good luck

Cardio, cardio, cardio. This helps you with the simple philosophy behind fat loss: Burn more calories than you take in. If your goal is fat loss, incorporate 4–6, 30–60-minute sessions per week into your training schedule.\n\nOf iron and sweat. If your goal is to lean out, follow your weight training with cardio. Since lifting depletes glycogen stores, your body is more likely to use fat as its first fuel source during cardio. Also, the combination of the two results in a higher caloric burn postworkout.\n\nTread heavily. What’s the best exercise and intensity to burn maximal fat? Researchers found that jogging on the treadmill at about 70% of your maximal heart rate, or MHR (subtract your age from 220 and multiply by 0.7 for your heart rate in beats per minute), was optimal, burning about 40 grams of fat per hour of exercise. Going above or below this intensity burned significantly less fat, as did pedaling on a stationary cycle, regardless of intensity.\n\nRun hungry. If you can stomach getting up earlier, perform cardio before your first meal of the day. Your body is most likely to use fat as the first energy source because your glycogen stores are depleted. If you’re concerned with muscle loss, take 10–20 grams of whey protein before your session, but stay away from carbs.\n\nPost-cardio burn. Following aerobic exercise, your resting metabolic rate remains elevated for anywhere from 60 minutes to about 12 hours, depending on the intensity and duration of the exercise session.\n\nMove outdoors. Try your next outdoor run on sand, which is more difficult than running on harder surfaces like cement. It’s easier on the joints as well, but wear shoes to avoid stress fractures and protect your feet from glass. Running on grass is also a welcome relief to joints and arches.\n\nTaper off. Instead of starting slow and building up speed, do your high-intensity cardio early in your workout and taper off to a slow finish to burn significantly more fat. After a 2–3-minute warm-up, immediately kick it into high gear (80%–85% max heart rate) for 15–20 minutes before slowing down (60%–65% max heart rate) for the last 10–20 minutes.\n\nVary your cardio. Whether you’re lifting weights or doing cardio, the trick is to keep your body from adapting to what you’re doing. Regularly changing your cardio mode is the best way to keep your body responding to your efforts.\n\nInterval for success. Unless you’re a highly conditioned athlete, you can’t maintain a very intense pace for very long, so the best way to improve your aerobic fitness and burn fat is with intervals. That is, you alternate very intense periods of work with lower-intensity sessions in which you recover.\n\nNo butts. Smoking deprives cells of the oxygen they need to maximize metabolism, keeps muscles from repairing themselves after exercise and makes cardio a lot tougher. Plus, your smoke-scented clothes are sure to irritate fellow gym rats.\n\nFidget to fight fat. Are you a fidgeter? Maybe you should be. Several studies have shown that toe-tappers, while completely annoying at the office, will burn more calories over the course of the day than the stationary man.\n\nNUTRITION\n\nStay hydrated. Active individuals actually require more water and should aim to consume roughly 1 gallon per day to avoid becoming dehydrated. And if you’re one of those people who hates drinking water, consider this: Dehydrated individuals burn less fat than their well-watered counterparts.\n\nEat more frequently. Eating 5–6 small meals a day as opposed to “three squares a day” causes your metabolism to work constantly. Eating larger meals, on the other hand, slows your metabolism and forces leftover calories to be stored as fat.\n\nEat protein. Since muscle-building is the fastest route to slim down, you want to make sure that your protein consumption is enough to keep up with your weight training. Eat too little protein and your gains could be much slower. Get 1–1

Depends on your goal and the current state of your body.\n\nIf your bodyfat percentage is less than 15% then you should concentrate on adding muscle. This means doing moderate cardio (not more than 3 times a week) and more weight training. Eat enough protein (at least 1g per lb of bodyweight). \n\nIf fat% is more towards the 20's then High Intensity Intervel Cardio for 20-25 min a a day is the answer. This should be done at least 5 days a week. Weight traininig is important too. Try not to do them in the same session as this is too taxing on the body.

This actually ideal if you can make the commitment to do so!\n\nDo your first session in the morning on an empty stomach.  Get on the treadmill or elliptical and  keep your heart rate between 130-140 bpm for 30-45 minutes.\n\nWait 60-90 minutes after done with morning cardio session before you eat to ensure your metabolism is taking full effect of the cardio you just did and continuing to burn fat. \n\nHit another 30-45 minutes session at night at the same resistance.

watch your diet first and foremost, 20-30mins of cardio excercise at least 3 days a week, and 5-10 mins of ab work at the end of every workout...

I do a lot of weight lifting and moderate cardio.  I want to have an average bodyfat but a high strength and above average build.  Sooo more weight lifting moderate cardio.  I have an entire weight lifting technique sheet that I keep saved on the computer if you like me to email it to you (i can't send attachments through here).  But keep your cardio 30-45 min overdoing cardio actually burns muscle and promotes cortisol (fat storing hormone) so overboard is bad(keep workouts/cardio total 1-1.5hrs).  The problem is keeping the diet in check because its one of the most important parts of keeping in shape.  \nIf your just starting out drink your water, drinking more water makes your body actually shed access water weight.  It tricks the survival mode of your body after it see's it gets water a lot it sheds what it doesn't think it needs anymore.  When working out or doing cardio weigh yourself before and after.  For every lb you loose drink 1 L of water throughout a couple hours(not all at one time). \nEat clean foods http://www.bodybuilding.com/fun/stella9a.htm \nand have 5-6 meals a day which boosts metabolism.  \nFor weight training if your looking at toning up high reps lower weight.  Work 1-2 muscle groups a day 4-5times a week (until you hit all bodyparts in the week).  Don't overdo your ab workouts.  Many times people do abs like everyday... this actually breaks down the muscles because they haven't fully healed and then you turn around the next day and work them again.  You need to lower your overall bodyfat and BUILD the abs which the best ab building technique is roman chair situps.  But here is a good list of more techniques http://www.bodybuilding.com/fun/abs1.htm\nOh forgot sleep... get your 7-8 hours every night.  when you sleep is the only time that your body recovers from all the cardio or lifting you did during the day.  Also working out in the morning burns more calories throughout the day than working out at night and going to sleep a few hours later.

My trainer set me up with weight-training three times a week and cardio two times a week.  She suggested alternating them and not doing them all at one time.  If it's possible, maybe you should try to go 4-5x a week, spread out your activites.  I also alternate what part to work out first each time I weight-train.  I'll start upper one time, lower the next.

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.

Cardio isn't going to tone you up much. It's more of an aerobic activity. You need weights. Weight training will allow you to tone your muscle, and/or add size and strength to them. Start with machine training if possible. You can do a full body workout 2-3 times a week with light weights for toning, or you can work upper body one day, rest day, legs next day, rest day, stomach and back, rest day, etc. If you stay with the same weight and do high reps for each exercise (20-25) you will tone. If you go heavier and do less reps (8-15) you can add strength and size.

do a LOT of cardio... like RUNNING and things like that.

You are right it is a great start. I go to the gym 7 days a week alternating days between cardio and weights.For the best results you should have both in your work outs. Go slow, keep it fun and change it up so you keep the intensity different for optimal results.
