Hey, thanks for the advice!

I worked out today, and went back to the original weight that I started with. I'm still feeling sore, but it's getting better. I have been doing PT exercises for my shoulder (car accident), but the gym didn't have any weights smaller than 5 lbs, so I used those. That could be the contributing problem, too. Today I did not use any weights for those exercises. I also think at least one machine is slightly too big for me (I'm 5'4"), and it is causing poor form. I will find an alternative to that machine.

It did occur to me today that the soreness might have been from the first work-out, but I really did not feel bad after it, and I didn't FEEL like I worked too hard.

I may not be eating well enough, because I do feel more hungry more often now. I am trying to cut calories. Although the diet plan I am on suggests 1200-1500, I already knew that would be too low, so I'm aiming for the 1700 range and give myself all the way to 2000 on some days, just to make sure I'm building good habits. Maybe I should allow more calories on work out days. Today I did 45 minutes on the treadmill rather than 30, and I am always hungry afterwards, even though I ate breakfast about an hour before!

So thanks! I will continue to study this.
