jogging, exercise machine, or biking?

Since you are trying to lose weight, the question is really which will burn more calories per session.  Whichever requires the body to do the most work is going to end up burning the most calories.  This figure is provded to us by something called METs (metabolic equivalents).  Overall jogging requires more METs than the eliptical, and the elipitcal requires more than biking.  SO jogging is going to burning more calories in the same amount of time than the other two.  \n\nHowever, either one of the other equipment could utilize more calories than jogging if you are exercising at a high enough intensity.  So if you are biking with a lot of resistance you will most likely burn more calories than if you are jogging at a slow rate of speed.\n\nThe best thing is to find an exercise that you like and are most likely to stay with.  Or better yet, mix it up and crosstrain.\n\nAs far as how long to exercise, it's not how long that's as important as how intense the workout is.  So instead of trying to exercise for an hour with a slow jog, you better better off going at short time period, but at a higher intensity.

Firstly you need an IPOD and secondly definately outside. Running can be sooo boring it's not the thing I like best but it's easier to run when you can be distracted by outside sites. \n\nI like to have a routine with heaps of variety and go to the gym 6 times a week. So, I normally am doing a run on the treadmill in between weight sets to get the heart rate pumping. Not my choice of activity that's for sure!

Probably the exercise bike as it doesn't put a lot of stress on the knee (as long as you don't put to much resistance on the flywheel/tensioner,also make sure your seat is the correct height you want to have a slight bend in your knee at full stretch.

I think swimming, though if you are not an avid swimmer it is difficult to really get in a good workout. Spinning is great because almost anyone can do it and get a good workout. If you want some real fun though get a bike and get in with a group doing road biking!

Do cardio exercise. Walking is fine.

I'm in the same situation, so I jog/run/hike.  And do pushups.  Anything that gets your heart rate up for 15-20 a day.  And diet is really important at our point in the weight-loss cycle.  We can't just do diet OR exercise, we have to do both.

For cardiovascular exercises you can walk, run, swim, bike, hike, do yoga and/or pilates, any aerobics class, elliptical, stairmaster, canoeing\n\nHope this helps.\nwww.jifitness.com

I had a professional measure and calculate different exercises for me in terms of most calories burned in shortest period of time.  Based on their calculations an eliptical machine was the best.  It was superior to treadmills, walking, swimming, bicycling and many other activities I had them check for me.  An eliptical machine gives a good cardio work out while you utilize your legs, arms, abs and many other muscles.  It is a smooth movement which keeps you from suffering impact injuries that can be associated with jogging and running.  So I say if your goal is weight loss or stabalization an eliptical is a good choice.  I combine my use of an eliptical with racquet ball, swimming, walking, bicycling, weight training, and yoga.  The combination is great!  For fastest calorie burn it's the eliptical.  All depends on what you want out of your exercise.

Cardio Pump or ABT (Abs, Bums Tums) are exercise classes that really get your heart rate up and are a lot of fun.  Pilates is supposed to be very good too, although I nevery quite got to grips with it.  Also, swimming about 20 laps everyday will tone you up all over.\n\nI've recently taken up running and that's been hard, although I'm determined to stick with it.\n\nBelly Dancing is a heap of fun and you do get a surprisingly good workout from it.  Where I live you can take lessons that have weekly evening classes over ten weeks, so maybe the same where you live.
