The number of calorie you burn during a workout is primarily dependent on intensity. The greater the intensity,the more calories burned.
The intensity is determined by your heart rate. The higher you drive your heart rate, the more calorie you burn.
Thus, you can get a good workout on almost any cardio piece as long as you keep you heart rate elevated.
The treadmill and elliptical are weight bearing exercises, which increase the work load/intensity.
You can get a bit more of a total body workout with the ellitical because of the arms on it.
However, the leg drive is tied to the arm drive on the majority of ellpiticals. What ends up happening is most individuals usually hold to the arms, allowing the legs to move the arms.
Rather than pushing and pulling with the arms, most individuals hold on…getting more of a passive upper body workout.
You can get you heart rate up on a bike but it is a little harder comparied to a treadmill or elliptical. That because you body weight is being supported.
‘You can elevate you heart rate on a bike but it more demanding.
