my butt is like a low ride car

I'm not skinny. I'm working on it, but I have some ways to go. I have decided when I run, I must look like one of those cars that has so much crap in the trunk that the trunk is only inches from the ground. That is how my butt feels. It always feels like it is pulling my back and down towards the ground. If only I could detach it! I would be so much faster!!! I'm not tall anyway, so it is close to the ground, but if I could just take it off and leave it at home for my runs, I could get them done so much more quickly.
