training wheels 

Little wheels that are installed in the back of bicycles, to the left and right, for kids who want to ride a bicycle but can't balance yet. With these wheels, they can ride without falling down. Eventually, they'll get rid of the training wheels when they get older, and they'll need to do that if they want to go faster and turn better.

Little Timmy is too young and keeps falling down with his bicycle, so we put training wheels on it.

Training for the Olympics

The act of taking a large healthy dump. This is usually a very long and painful process.

Where the hell is Leroy? We were supposed to meet here 20 minutes ago.

He had Chinese food last night and he wanted me to tell you that he'll be training for the Olympics this afternoon.
