PRACTICE: The American Sign Language (ASL) sign for "practice / training"
 

PRACTICE or training:
The right "A" hand brushes up against the top side of the left index finger. The motion is similar to polishing a shoe. Think of "polishing up your skills."

Sample sentence: MOLLY PRACTICE BIKE, NOW THINK EASY.

TRAINING:
If you do the sign "practice" using a right "T" hand, it specifically means "training."
Some people might consider this to be "Signed English." Most of the time you wouldn't need a "T" to establish the meaning of training because the context of the sentence would tend to clarify whether you mean training or practice.
