New Direction, or rather "a" direction

I haven't posted for awhile and am at a loss of what to write about because it has been so long. I have decided that I would dedicate this blog to my experiences at the gym and the whole getting healthy, losing weight thing. Today I went to a "power pump" class, the same class I attend every Monday and Wednesday that I don't have to work. She teaches on Fridays too but every day is dedicated to a specific area of the body and Fridays are chest. They do a shitload of push ups, not girl pushups, boy pushups. NOT FOR DARCIE! Today was shoulders, legs, and abs. I think I should just throw in the towel now. It seems as if everyday it gets harder to keep up with the instructor, not easier. Doesn't it make more sense that if you are becoming stronger and more fit you would be able to "do" more. Not so much. I don't want to sound catty but there are a couple of girls who come to class who are pushing 230 and they can keep up. WTF??? During the bazillion squats we did I had to take a couple of breathers. To be honest I thought I was going to squat and continue downward until I was on my face. But that big girl kept on a trucking. Can someone explain this?
I hadn't done any cardio in awhile so I thought that I would fit some in after the class but before I had to get Tel out of the daycare there. 25 minutes of level 7 around the world biking ended up being 20 minutes. I guess 20 is better than nothing but now I am sulking around my house wishing I could take a nap and knowing that I was going to mop floors but have no energy to do so. Besides after the hour of shoulder presses I probably could not lift the mop to wring it out. Maybe Friday...
