The alternating plate reach increases strength and stability through the core. The exercise also improves strength in the shoulders and triceps.
Place each hand on top of a weight plate and get into a pushup position. Your body should form a straight line from your shoulders to your ankles.
Slide one arm out in front of you and bend the other elbow, lowering your body to the floor. Your shoulders should remain parallel to the floor and your body should still be in a straight line. Raise your body back up by extending the bent elbow and pulling the other hand back to the starting position.
Focus on creating a full range of motion.
Squeeze your abs and glutes throughout the movement for stability.
