| Sprint intervals or straight jogging...
what burns more fat and boosts your metabolism?
I am currently doing sprint intervals on the treadmill for about 25 mins. 1 min sprint, one minute standing on the side not running at all, then hop on to treadmill and sprint again for one minute, etc...
Is this better than jogging at a good pace or the same or not as good? I had a trainer once tell me it'd shape me up pretty damned fast if I did it a lot.
