Cross Trainer and just back in the gym?

[hicarbon]

Was just curious, is it normal for someone who is really out of shape, doesn't eat right (Trying to start) and doesn't get much exercise, to feel like they're about to throw up after 10min. on the cross trainer and burning 111 calories? I had just gotten done doing some minor chest exercises (chest press with dumbells, etc.) and after about 5min., jumped on the eliptical to do some cross training and after about 10min., my stomach felt horrible. So I got off and cycled for about 10-15min. I was sweating like CRAZY already (which isn't normal for me, but then again I hear the eliptical really gives you a cardio workout) and trying to keep hydrated and all, but I could only do about 10-15min. on the cycle before I had to stop altogether and call it a night.....

So is this normal? and, is it ok to keep doing smaller workouts like this as I build myself up? I'm trying to start eating right (watching my calorie intake throughout the day so that I can monitor how much I'm taking in versus how much I'm burning during the workout) and going to start working out as often as I can (but being safe about it). And also, how do you figure out around how many calories you may burn with weight training?? I don't lift anything heavy at all as I am just back in and taking it easy at first to build up....Thanks everyone!

I get that way if I have too much caffeine (coffee or tea) and not enough sugar. An infusion of sugar like a candy bar and coke gets rid of it real quick. I try to watch it so I don't have to deal with the feeling. Like in the the morning I eat oatmeal with 3 tea spoons sugar before working out. I have a banana or apple between 9 and 10am, lunch at 12, snack between 2 and 3, etc. Just keeping my sugar level steady during the day keeps the sick feeling away.

It can also happen if you are a bit sick. Cold, flu or sinus problems could be the cause.

If you havent worked out in a long time or very often, then it is ok for you to start off easy. You dont want to over do it and make yourself hate working out. It is normal for you to be feeling tired especially if you are out of shape. I would recommend walking on the treadmill first or biking at a low intensity until you build up some endurance. It is not going to be easy getting back into shape, but as long as you slowly progress, you'll fitness will improve greatly. It is very hard to tell how many kcals you burn while weight lifting. The ACSM (American College of Sports Medicine) estimates that it ranges from 4 to 10 kcals/min while engaged in actual weight training. This does not include rest intervals and is proportional to the amount of muscle mass involved.
