For waitressing, how do I hold my hot, heavy trays while handing the food out to the tables?

I've been working at Cracker Barrel for a month now as serving assistant. Now I'm upgrading to server and I just started training today. I was doing good up until I spilled a Coke on a customer. The only thing I have a hard time with is carrying the hot heavy trays. Even with the round trays i have a hard time handing out the food while holding the tray. So please help me. I need to know how to be a better server. My trainer just told me instead of trying to balance the tray just rap my arm under and around they tray, well that's a probl;em because my arm is not long enough to be doing that. I know I have enough strength for this job because I work out all the time, so I need to know what is wrong with me and how I can fix my problems?!
Thanx,
Jacque

If you can put the tray on a nearby (unoccupied) table, that's great, or ibetter, get one of the tray horses. When you're carrying it, I find the most stable way to support a big heavy tray is to rest one side on your shoulder and hold the other side with the hand on the same side. Use your other hand to balance the tray while walking if necessary, but don't feel at all shy about putting the tray down when you get to the table. You're not gonna get more points or a bigger tip if you hold the tray instead of putting it down, and you'll get less if you spill food on your customers.
