# Lock (waltz)

There are several types of lock step in waltz dancing, including International Standard waltz. A "lock step" is when the moving foot approaches to the standing foot and crosses in front of or behind it, creating a "check" position.
There are several locking steps in waltz, including: the back lock, which is a Bronze syllabus figure; the turning lock, of the Silver syllabus; and the turning lock to right, of the Gold syllabus.

## Back lock

The back lock is a Bronze syllabus step. It is a progressive figure borrowed from quickstep. It is commonly used as the ending to a progressive chassé to right.
