TECHNIQUE: Feet are hip width apart, weight in the heels and midfoot, arms straight with palms gripping opposite ends of the dumbbells. Keeping your core engaged and chest up, hinge at your hips doing a slight jump bringing the heels together. Finish with hip extension and bring the dumbbell up with the opposite grip. ADVANTAGES: Thread the needle is a great movement to build aerobic endurance with light weights. FAULTS: Common faults include gripping the inside of the dumbbell, missing the feet coming together and then back out, and arms moving before hips. SCALING: Movement can be scaled down by removing the feet coming together.
