work better, or that interval training you talked about. I mean... it's all about how much calories you actually spent right?
there's a lot of research supporting various forms of interval training as more effective. interval training on an elliptical machine helped me when i was trying to strip a lot of bf% at once, but i also was neglecting leg workouts at the time.
I'm trying to switch between ellipticals and treadmills. I noticed that ellipticals is more taxing on your muscles themselves, almost feeling as though you just weight trained your legs, while treadmills, especially running at high speeds, is more taxing on your overall body and your breath rate/blood flow.
the standard settings on most ellipticals can be kicked up in terms of resistance to increase the stress on your cardiovascular systems. moving your arms -- or using a machine that has moving handholds -- will involve more of your body. personally, i find the moving handholds annoying & i can never quite adjust to the motion, esp. as exhaustion builds. but let go of the handrails and let 'em swing.
the chief advantage of an elliptical, as i see it, is that it should be significantly gentler on the knees, esp. for heavy guys or those who, say, ran hurdles for many years.
I'm not sure which one is better overall to lose fat, but I can work out about 520 calories in 30 minutes on the treadmill while only about 430 calories on the elliptical.
such numbers are nearly meaningless. you can rarely tell whether or not they're including (or trying to estimate) your bmr (baseline metabolic rate). more intense exercise burns calories for a much longer period after you stop exercising, but also slams your recovery systems, which can affect gains from lifting, if that's a part of your program. such numbers can't (or shouldn't try to) factor in either consideration.
Also, the ellipticals doesn't really train your ankles or your calves as well, but supposedly it should in theory use more of your calories with the same amount of effort (according to articles).
depends on the machine, the settings, and your stride. you can certainly make either or both work much harder by intentionally involving them in the stride.
Which one you guys prefer?
riding my bike, walking, or jogging lightly on a dirt path or a very slightly squishy oval track (in good condition). an elliptical in a very desperate pinch (say, 48 inches of snow on the ground; everything covered in ice; or temps above 100degF and/or ozone alert, and i'm stuck exercising midday), out of continuing deference to my knees. otherwise, anything outdoors. also swimming, tennis, racquetball, basketball......
