ALTERNATING REACH AND CATCH
Form cues
About
The Alternating Reach and Catch is a reactive hand-eye coordination drill that trains unilateral reaching patterns, rotational core control, and rapid hand placement under cognitive load. Often used in athletic performance training, fall prevention, and pediatric development, it challenges the nervous system to produce accurate reaching movements in response to an unpredictable stimulus — developing the reflexive stability that protects joints during unexpected movements in sport and daily life.
Instructions
Step-by-step technique
Prepare your starting position
Lie flat on your back on a mat with your knees bent and feet planted firmly on the floor. Keep your arms extended down by your sides and maintain a neutral spine, ensuring your lower back remains in contact with the mat throughout the movement.
Back flat on floorInitiate the controlled crunch
Engage your core to lift your head and shoulder blades off the ground, simultaneously reaching both hands forward toward the outside of your right knee. Focus on using your abdominal muscles to generate the movement rather than pulling with your neck or shoulders.
Exhale as you liftLower back to start
Slowly reverse the movement by lowering your upper body back down to the mat with control, keeping your core engaged to prevent your back from arching. Avoid using momentum or letting your head drop suddenly as you return to the starting position.
Control the descentReach to the opposite side
Repeat the crunch movement, this time reaching both hands toward the outside of your left knee to engage your obliques. Ensure your feet remain grounded and your movement path is steady to maximize the activation of your lateral core muscles.
Keep feet plantedMaintain rhythmic and deliberate tempo
Continue alternating sides for the prescribed number of repetitions, focusing on precision and reflexive stability with each reach. Keep the pace slow and steady to ensure your abdominal muscles are performing the work instead of relying on swinging motions.

What goes wrong — and why
Reaching with a rounded spine
Collapsing the thoracic spine forward during the reach reduces reach distance, compromises rotational ability, and places the shoulder in a compromised position.
Maintain an upright torso and rotate from the thoracic spine and hips. The reach should come from rotation and shoulder extension, not spinal flexion.
Planting the feet and not rotating
Refusing to allow any lower body movement limits reach distance and prevents the trunk rotation that gives the drill its core training benefit.
Allow a pivot step on the ball of the foot toward the target. Natural rotation should flow from the foot through the hip and into the reaching arm.
Tensing before the stimulus
Anticipating the target and pre-loading the catching arm removes the reactive element, which is the primary training benefit of this drill.
Stay loose and neutral between catches. The drill trains reaction, not prediction — let the stimulus drive the movement.

Adaptations for every level
Seated Reach and Touch
Perform in a seated position to remove balance demands and focus on rotational reach pattern development.
Lateral Medicine Ball Toss
Replace the reach with a lateral wall toss and catch using a medicine ball. Adds loading and a power component to the rotational reach pattern.
Single-Leg Reach and Catch
Balance on one leg while alternating reach and catch. Combines single-leg stability with reactive coordination for a high athletic demand.
