I'm currently working out on the elliptical for an hour 4 times a week ... this burns 700 calories. I know i need to add some weigh training,etc but i havent gotten that far yet, I've only been working out for 2.5 months so far. Would i get more out of doing the elliptical for 1hr at 700 calories ... or doing the elliptical for 45 minutes and then the treadmill for 25 minutes for the same 700 calories burned? I'm a 24 yr old female trying to burn fat!
