Simple cognitive exercises: Memory, attention, logic, or reasoning tasks sharpen mental processing speed. Simple movement exercises: Repetition-based drills like throwing and catching a tennis ball off a wall build coordination. Reaction exercises: Using reaction lights like ROX or ROXPro to combine sensory input with movement. Concentration exercises: Juggling 2–3 balls helps improve timing, decision-making, and focus. Wall Ball CatchThrow a tennis ball against a wall and catch it with the same hand. This simple drill boosts hand-eye coordination and quick reactions. Light-Based Reaction Training (e.g., ROX)Use randomized light cues from A-Champs solutions and respond with touches, steps, or throws. JugglingPractice juggling with two or three balls. It enhances peripheral vision, concentration, and overall reaction time in sports like soccer or tennis. Partner Drop DrillHave a partner drop a ball or ruler unexpectedly. Catch it as quickly as you can—an effective way to measure and improve response time. Dual Task Balance DrillStand on a balance board and react to auditory or visual cues.
