When it comes to losing fat, the best cardio you can do is the one you hate the least (and the one with the lowest chance of hurting you). Barring that, it seems as though running melts the pounds off the fastest.
British scientists compared two groups of fit men—one ran on a treadmill while the other used a cycling ergometer. Both groups exercised at sim-ilar levels of intensity as measured by their oxygen expenditure. At the end, the running group burned significantly more body fat than the cyclists.
The scientists suspect that running uses more muscles and muscle fibers than cycling does. That’s why more fat is burned while running. Cy-cling seems to utilize more glycogen for fuel as opposed to fat stores. This doesn’t mean you have to run at all costs. Gait mechanics can be tricky to learn, and some people are too prone to injury to make running worthwhile. If you tolerate the tread-mill, go ahead and use it, but a good workout on a rower, StairMill, SkiErg, or Airdyne can burn a ton of fat and calories as wel
