The treadmill burns a lot more calories by far.

The cross trainer is better for burning calories faster.  It also works more of your leg muscles.  However, if training in intervals on an incline the treadmill can be beneficial; but can also place a strain on your knees.  With all things being equal the cross-trainer is better on your knees, tones you easier, and burns more calories.  I normally use the cross trainer for 30 minutes as part of my cardio, but I always finish with an easy 10 min walk on the treadmill.

2000-2300 depending on lifestyle.  More active=more calories\nless active=less calories

It's hard to say without knowing your condition, but if you are big and lean you could be burning 400-500 cals per hour, but, if you are light and/or have a high bodyfat ratio it may only be 200...\n\nIn my experience I have seen a 200 lb man that is very lean  burn about 1000 cals per hour during VERY intense exerscise.  \n\nHere's a calculator for you to try http://www.primusweb.com/fitnesspartner/jumpsite/calculat.htm

I have worked out both on the revolution and the older bow flex model. Both are a great substitute for free weights. They both require they use of stabilizing muscles unlike most machine which in turn provide a better work out than most machines. If you cannot afford a gym membership I feel like this is the most economic solution. It is worth the price for for results.

You may need to work out longer on a recumbent bike because you are sitting down so you are burning less calories (and using less muscle).  However, if you are running on the treadmill, a recumbent bike is a lower impact exercise and might be better for your joints and bones.

Cycling, like all exercises, burn calories. Cycling burns approximately 400 calories per hour (9 mph). It will help in trimming your waist, as well as your whole body, with the right diet.

If your goal is "strengthening" as you say, then biking would be better. Biking offers more resistance and stress to the muscles of both the legs and arms. Reistance and stress on the muscles build muscle and strength. \n\nIf you are just starting a fitness program from a fair inactive lifestyle, you might want to consider walking as a "first step."

some heart rate monitors will calculate calories burned.  it may be off by a couple percent but it will give you an idea.\n\nfor me 180lbs on a good road bike:\nrecovery (slow 14mph) about 400 to 500 for an hour\nfast (race or hard group ride) up to 1000+ an hour

You can burn 800 calories an hour using a cross trainer on level 5+ as well...

The 'fat burning zone' is the biggest myth ever!!\n\nHigher intensity exercise will still burn more fat calories proportionally because it burns more calories in total.\n\nSay you work with a THR(target heart rate) of 130 BPM(beats per minute) for 30 minutes you may burn off say 100kcals for arguments sake. Out of those calories a higher percentage will be fat calories. say 70kcals are fat calories with me?\n\nThen say you do a workout with a THR of 170 BPM for a shorter duration of time say 20 minutes and you burn maybe 250 kcals. A smaller percentage of these calories will be fat calories BUT on the whole you will still have burned MORE fat calories and MORE total calories as oppose to lower intensity 'fat burning'.\n\nPlease note that the calorie expenditure for above is very rough and only used to explain how things work, body composition also comes into play.\n\nSo basically a higher intensity CV workout (interval is even better) will burn off more fat calories and more total calories than a so called lower intensity fat burning programme.\n\nI hope i made sense in trying to explain myself!!

How many calories you burn will be specific to each person.  On average though running will burn more than bicycle riding. Men burn faster than women, heavier people will burn more than thinner people.  You will need to find a chart that you can adjust for your sex and weight and other factors.\nBicycle riding at 5.5 MPH will burn about 450 calories per hour\nRunning at 11:30 minute mile pace will burn about 700 calories per hour.

Unfortunately you can't tell how many calories are burned with your heart rate that I know of, I could be wrong tho, it's happened before! lol  \n  If you go to your yahoo search engine and type in "calorie expenditure chart" you'll see some charts there for calorie burning.  If spinning isn't on the chart, just double what you see for bike riding.  Good for you-spinning is a great fat burner, and what it does for your legs is unbelievable!  good  for you!

You are looking for the amount of work done by the bicycle.\nWe know this value will be less than 5.4X10^3 J because energy is always lost when using a machine.\nIn addition, the answer is equal to the efficiency (62%) times the amount of work the cyclist does. \n(I wouldn't be right if I did your whole homework problem so I'll stop here)

Try the "Shape of Your Life" program by Outside magazine.  This program has you working on endurance, speed, stamina, strength, and balance.  All of these will improve your cycling.\n\nAlso, interval workouts on the bike will make you faster and stronger.  There are a lot of good sources describing these types of workouts.  These are relatively short workouts that yield huge returns.

Well, I am a cyclist and this is kind of cliche, but Lance Armstrong.  The man won Tour de France for the seventh time in a row.  A very tough event which covers three weeks, more than two thousand miles, with just two days "off" which are used to travel, and through the Pyrenees and French Alps!  He and other professional cyclists train many tens of thousands of miles each year, burning around about a thousand calories per hour, lots of pain to add.  The longest stage in 2005 was over 140 miles, and mind you, the day before that stage was also over 140 miles as well.  This is with no commercial breaks, time outs, half times, substitutions, or any other sort of break other than a crash if you are unfortunate to get into one.  They even have to eat during the course of the race!  And I could go on...  Lance has this event seven times.

i think ridding a bike is the best exercise.
