How to perform it

Set two or more targets around a central starting point, far enough apart to move but close enough to reach under control. Rehearse each direction before adding speed or a partner's call.
From a balanced ready position, use a small split-step and push towards the chosen target. On a called repetition, react to the signal instead of committing before it arrives.
Shorten the approach steps and lower through the hips and knees before the reach. Keep the loaded knee tracking with the toes and let your body turn as the reach requires, rather than forcing your chest towards the front wall.
Reach towards the target from a stable lunge or side step; keep the target within a range you can control. A low hand touch is optional, not a reason to collapse at the waist.
Push back to the central starting point and regain balance before the next direction. Work to both sides, keeping the movement smooth as the direction changes.

Common mistakes

Changing direction at full speed without braking first.
Reaching far beyond the supporting foot and losing control of the trunk.
Letting the loaded knee fall inward, or twisting the trunk while the foot stays fixed.
Guessing a partner's call or rushing into the next repetition before regaining balance.

Skip or adapt this movement if any of these apply — and check with a professional when in doubt.
