Sorry guys, just had to make a post. Got off the scale and I lost enough to make 1 hp on the R450. I drive a lot for work so I've put on a few pounds during the last 2 years on the road. By the time I'm back in my old shape I will have gained 4.2 hp. If that doesn't make you want to run an extra mile on the treadmill I don't know what will.
