Eliptical sprint and fat loss

[muscledog95]

It seems common knowledge that sprinting is oneo f the best for fat loss and cardio. however, sprinting is rough on the knees. Would going extremely fast on the elliptical machine yield the same results?

Thanks

depends on what level you set the resistance at........I really don't think spinning or Elliptical is a replacement for sprints
