Hey, new here, and i need to ask a question. I've been working out the last month, I WAS 260 lbs, now im 246-245 lbs, and mostly I've been taking in very little calories (usually between 500-1000 a day including workout) and working out on a 1000 calories workout. I use a DDR machine, and to be honest I thought those they were resourceful, but when I tried to do it on an olyptical (sp) machine, a felt a more signficant amount of struggle in an earlier time and saw I was burning less calories but was being as long as I usually was on a 1000 calorie workout on DDR. My question is is DDR a reliable way to work out? I'm trying to lose 60-80 lbs, and even though I'm doing good, I'm worried (now that most of my water weight is gone) that I will not be working out effectively. Can anyone help me with this?
