What muscles are used passing a rugby ball?

Answer 1

Upper body mainly. Deltiods. If passing off right arm to the left your right arm would contract using the anterior deltiod, the left arm would contract using the posterior deltiod. Other muscles used would be the wrist flexors, pronator teres, biceps and triceps. Possibly trapizius. Pectorals.
