call me whatever you want but i am looking for real advice. i've started to incorporate some cardio into my diet and I'm wondering if it's too sloppy. Pretty much what I do is run/jog/speedwalk on a treadmill until I've burned at least 600 calories. I can do about 600 in an hour (I know this may not sound like a lot but it's what I can do). Should I shoot for more? Should I focus on sprinting or something? 18m 5'11'' 155lbs looking to get to 130 as fast as possible (started at 185) currently eating 1,000-1,200 calories/day (should I restrict more too?)
