Uhm. Is there any chance that maybe the class itself just really sucked? Just a thought.
Have you worked with a trainer who is aware of your current level of fitness and understands where you want
To be honest, I HATE taking classes. The pace is either too slow, too light, too boring, or too something. It isn't always because of the instructor either. They have to teach to the middle and sometimes a class can be too much for some and not nearly enough for another.
Perhaps once you learn form, technique, and how to fine tune your workout for yourself you may enjoy your lifting more. I really just can't follow someone else's lead through a class. Love to learn new things and one on one is great for me but a group. ~sigh~ Somehow I just really resent having someone else "pace" the workout for me.
It also helps to be healthy and not coming down with a cold.
I'm usually lacking enthusiasm for my workouts just before a cold hits too. Hang in there, the benefits are just wonderful that if you have the opportunity to add strength training to your workouts do so! Really give it your best shot for at least two months and then decide if you really hate it. In the meantime, check out Krista's site www.stumptuous.com

Best of luck!
