Players on baseline. Coach calls a line ('half-court!', 'free throw!', 'three-point!'); players sprint, touch with hand, sprint back. Random order.
Reaction-based conditioning. Builds explosive change of direction.
React fast, first step matters.
Touch with a hand, no cheating.
Low on the turn.
Return HARDER than you went out.
Listen actively, don't drift.
Coach fakes a call. Multiple lines in one go. Add ball-handling. Reverse: slides out, sprint back.
