Shuttle Run
Step 1
Set two markers the desired distance from each other. Stand behind one of the markers and face the direction of the second marker. This is your starting position.
Step 2
Run from the first marker toward the second marker, and touch the floor past the marker with either your hand or foot — whichever is most comfortable.
Step 3
Turn, face and run toward the first marker to return to the starting position. Repeat for the specified amount of time.
