RE: Best equipment for fatloss?
no. natural running is about pushing your sel forwrds as well as up and down. you need a 3%incline on a treadmill to have the same effect as running on the flat asphalt. even then, they really don't compare.
i'm with vovoid on this one, buy the very best pair of RUNNING* trainers you can aford.
*does not include the likes of £120 nike air max etc etc. go to a proper sports shp and get some asics, merrel or solomon.
