Time to get serious

So in talking with a bunch of the coaches at the gym they seem to think that I would be a better fit fighting at 205 rather then heavyweight. Which sucks because I've really trimmed up lately, and yet I haven't lost any weight even though I've been told I'm noticibly smaller...So what that means, is that I have to go on an all out weight blitz. I weigh 260 right now and I would need to get to 220 so that I could cut 15 lbs of water weight for 205. Seems tough but it will probably be good for me. Also the coaches are absolutely correct, I don't have the body type to fight at heavyweight, I don't have the reach etc. So we'll see if I can make this cut and learn to punch and we'll find out what happens.
