Why I have failed in the past (and will succeed now!)

So, I went to the gym yesterday to do a step aerobics class. I really do like the people at the gym I go to, but as you can tell, it hasn't done anything for me. I actually weigh more now then I did when I started three years ago. This is why the traditional gym setting hasn't worked for me;

My consistency is on and off. There is no accountability. I work to the level I want (easy) and then I'm done. I don't really know what the heck I'm doing, so I would move from machine to machine and without ever getting any results. I stop going because I don't get results. I don't really change my eating. I also was watching the personal training yest. and they do it right in the middle of the floor. NEVER would I have ever signed up for that because I would find that so embarrassing. I love that Fitness Together is a private space and I don't feel like everyone is staring at me. Working with a trainer pushes me to work at a level I would NEVER work out at alone. NEVER, NEVER, NEVER. Not even close.
So, that is my rambling for today, but I thought that was important to share. I need to learn why I have failed in the past, so I can succeed now. ;0)
