A little background: I'm 19 and not "overweight" but looking to lose 7-8lbs(which would put me at 19.3 BMI). I've currently got a BMI of 21. On March 1st I started a bit of a diet/workout routine. I was/am eating about 1200 cals a day (I've had a few slip ups, I'm a chronic comfort eater) and doing an hour on our Gazelle Cross trainer every day. My weight hasn't changed much from when I started, but I noticed a big change in my thighs and upper arms. They look much less flabby/tighter.
I'm very comfortable with the Gazelle, and have no problems getting to an hour or an hour and a half on it, at a fairly good speed(though I still end up sweating a bit and being tired). Recently we bought an elliptical and I struggle to complete even 5 minutes on it. I got to 15 the other night and was having chest pains and shaking. My father on the other hand has worked out less, and has a BMI of 29, yet he managed to do 15 minutes on it tonight with surprisingly little strain.
Am I just really, really, out of shape? I do understand the that gazelle has no resistance, while the elliptical does. But the degree of exhaustion I'm experiencing is frustrating. I'm curious as to how long it'll take til I build up enough endurance to do it for longer.
