We do ladder drills: single/double/triple knees, shuffle step, shuffle step out, turning steps. For speed, add a medicine ball to the mix.
In the beginning of class, we often do chun jin, who jin, ilbo chun jin, ilbo who jin, and running step drills.
These drills are a great warm-up and sometimes we will do teams so that one person is going up and down the floor and they they hand-off to the next person, sort of like a relay race. Nothing like competition to make someone move faster.....
